I don't understand why that is important, and I would go with the text
that SPDX has on file, as long as both contain the same content.

That being said…

LGPL-2.1-or-later is used in at least two files in the tree…

I'd also opt to move to the new-style "LGPL-2.1-or-later" from here, as
"LGPL-2.1+" is deprecated since SPDX 3.0.

> -
> -Preamble
> -
> -The licenses for most software are designed to take away your freedom to share
> -and change it. By contrast, the GNU General Public Licenses are intended to
> -guarantee your freedom to share and change free software--to make sure the
> -software is free for all its users.
> -
> -This license, the Lesser General Public License, applies to some specially
> -designated software packages--typically libraries--of the Free Software Foundation
> -and other authors who decide to use it. You can use it too, but we suggest
> -you first think carefully about whether this license or the ordinary General
> -Public License is the better strategy to use in any particular case, based
> -on the explanations below.
> -
> -When we speak of free software, we are referring to freedom of use, not price.
> -Our General Public Licenses are designed to make sure that you have the freedom
> -to distribute copies of free software (and charge for this service if you
> -wish); that you receive source code or can get it if you want it; that you
> -can change the software and use pieces of it in new free programs; and that
> -you are informed that you can do these things.
> -
> -To protect your rights, we need to make restrictions that forbid distributors
> -to deny you these rights or to ask you to surrender these rights. These restrictions
> -translate to certain responsibilities for you if you distribute copies of
> -the library or if you modify it.
> -
> -For example, if you distribute copies of the library, whether gratis or for
> -a fee, you must give the recipients all the rights that we gave you. You must
> -make sure that they, too, receive or can get the source code. If you link
> -other code with the library, you must provide complete object files to the
> -recipients, so that they can relink them with the library after making changes
> -to the library and recompiling it. And you must show them these terms so they
> -know their rights.
> -
> -We protect your rights with a two-step method: (1) we copyright the library,
> -and (2) we offer you this license, which gives you legal permission to copy,
> -distribute and/or modify the library.
> -
> -To protect each distributor, we want to make it very clear that there is no
> -warranty for the free library. Also, if the library is modified by someone
> -else and passed on, the recipients should know that what they have is not
> -the original version, so that the original author's reputation will not be
> -affected by problems that might be introduced by others.
> -
> -Finally, software patents pose a constant threat to the existence of any free
> -program. We wish to make sure that a company cannot effectively restrict the
> -users of a free program by obtaining a restrictive license from a patent holder.
> -Therefore, we insist that any patent license obtained for a version of the
> -library must be consistent with the full freedom of use specified in this
> -license.
> -
> -Most GNU software, including some libraries, is covered by the ordinary GNU
> -General Public License. This license, the GNU Lesser General Public License,
> -applies to certain designated libraries, and is quite different from the ordinary
> -General Public License. We use this license for certain libraries in order
> -to permit linking those libraries into non-free programs.
> -
> -When a program is linked with a library, whether statically or using a shared
> -library, the combination of the two is legally speaking a combined work, a
> -derivative of the original library. The ordinary General Public License therefore
> -permits such linking only if the entire combination fits its criteria of freedom.
> -The Lesser General Public License permits more lax criteria for linking other
> -code with the library.
> -
> -We call this license the "Lesser" General Public License because it does Less
> -to protect the user's freedom than the ordinary General Public License. It
> -also provides other free software developers Less of an advantage over competing
> -non-free programs. These disadvantages are the reason we use the ordinary
> -General Public License for many libraries. However, the Lesser license provides
> -advantages in certain special circumstances.
> -
> -For example, on rare occasions, there may be a special need to encourage the
> -widest possible use of a certain library, so that it becomes a de-facto standard.
> -To achieve this, non-free programs must be allowed to use the library. A more
> -frequent case is that a free library does the same job as widely used non-free
> -libraries. In this case, there is little to gain by limiting the free library
> -to free software only, so we use the Lesser General Public License.
> -
> -In other cases, permission to use a particular library in non-free programs
> -enables a greater number of people to use a large body of free software. For
> -example, permission to use the GNU C Library in non-free programs enables
> -many more people to use the whole GNU operating system, as well as its variant,
> -the GNU/Linux operating system.
> -
> -Although the Lesser General Public License is Less protective of the users'
> -freedom, it does ensure that the user of a program that is linked with the
> -Library has the freedom and the wherewithal to run that program using a modified
> -version of the Library.
> -
> -The precise terms and conditions for copying, distribution and modification
> -follow. Pay close attention to the difference between a "work based on the
> -library" and a "work that uses the library". The former contains code derived
> -from the library, whereas the latter must be combined with the library in
> -order to run.
> -
> -TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
> -
> -0. This License Agreement applies to any software library or other program
> -which contains a notice placed by the copyright holder or other authorized
> -party saying it may be distributed under the terms of this Lesser General
> -Public License (also called "this License"). Each licensee is addressed as
> -"you".
> -
> -A "library" means a collection of software functions and/or data prepared
> -so as to be conveniently linked with application programs (which use some
> -of those functions and data) to form executables.
> -
> -The "Library", below, refers to any such software library or work which has
> -been distributed under these terms. A "work based on the Library" means either
> -the Library or any derivative work under copyright law: that is to say, a
> -work containing the Library or a portion of it, either verbatim or with modifications
> -and/or translated straightforwardly into another language. (Hereinafter, translation
> -is included without limitation in the term "modification".)
> -
> -"Source code" for a work means the preferred form of the work for making modifications
> -to it. For a library, complete source code means all the source code for all
> -modules it contains, plus any associated interface definition files, plus
> -the scripts used to control compilation and installation of the library.
> -
> -Activities other than copying, distribution and modification are not covered
> -by this License; they are outside its scope. The act of running a program
> -using the Library is not restricted, and output from such a program is covered
> -only if its contents constitute a work based on the Library (independent of
> -the use of the Library in a tool for writing it). Whether that is true depends
> -on what the Library does and what the program that uses the Library does.
> -
> -1. You may copy and distribute verbatim copies of the Library's complete source
> -code as you receive it, in any medium, provided that you conspicuously and
> -appropriately publish on each copy an appropriate copyright notice and disclaimer
> -of warranty; keep intact all the notices that refer to this License and to
> -the absence of any warranty; and distribute a copy of this License along with
> -the Library.
> -
> -You may charge a fee for the physical act of transferring a copy, and you
> -may at your option offer warranty protection in exchange for a fee.
> -
> -2. You may modify your copy or copies of the Library or any portion of it,
> -thus forming a work based on the Library, and copy and distribute such modifications
> -or work under the terms of Section 1 above, provided that you also meet all
> -of these conditions:
> -
> -      a) The modified work must itself be a software library.
> -
> -b) You must cause the files modified to carry prominent notices stating that
> -you changed the files and the date of any change.
> -
> -c) You must cause the whole of the work to be licensed at no charge to all
> -third parties under the terms of this License.
> -
> -d) If a facility in the modified Library refers to a function or a table of
> -data to be supplied by an application program that uses the facility, other
> -than as an argument passed when the facility is invoked, then you must make
> -a good faith effort to ensure that, in the event an application does not supply
> -such function or table, the facility still operates, and performs whatever
> -part of its purpose remains meaningful.
> -
> -(For example, a function in a library to compute square roots has a purpose
> -that is entirely well-defined independent of the application. Therefore, Subsection
> -2d requires that any application-supplied function or table used by this function
> -must be optional: if the application does not supply it, the square root function
> -must still compute square roots.)
> -
> -These requirements apply to the modified work as a whole. If identifiable
> -sections of that work are not derived from the Library, and can be reasonably
> -considered independent and separate works in themselves, then this License,
> -and its terms, do not apply to those sections when you distribute them as
> -separate works. But when you distribute the same sections as part of a whole
> -which is a work based on the Library, the distribution of the whole must be
> -on the terms of this License, whose permissions for other licensees extend
> -to the entire whole, and thus to each and every part regardless of who wrote
> -it.
> -
> -Thus, it is not the intent of this section to claim rights or contest your
> -rights to work written entirely by you; rather, the intent is to exercise
> -the right to control the distribution of derivative or collective works based
> -on the Library.
> -
> -In addition, mere aggregation of another work not based on the Library with
> -the Library (or with a work based on the Library) on a volume of a storage
> -or distribution medium does not bring the other work under the scope of this
> -License.
> -
> -3. You may opt to apply the terms of the ordinary GNU General Public License
> -instead of this License to a given copy of the Library. To do this, you must
> -alter all the notices that refer to this License, so that they refer to the
> -ordinary GNU General Public License, version 2, instead of to this License.
> -(If a newer version than version 2 of the ordinary GNU General Public License
> -has appeared, then you can specify that version instead if you wish.) Do not
> -make any other change in these notices.
> -
> -Once this change is made in a given copy, it is irreversible for that copy,
> -so the ordinary GNU General Public License applies to all subsequent copies
> -and derivative works made from that copy.
> -
> -This option is useful when you wish to copy part of the code of the Library
> -into a program that is not a library.
> -
> -4. You may copy and distribute the Library (or a portion or derivative of
> -it, under Section 2) in object code or executable form under the terms of
> -Sections 1 and 2 above provided that you accompany it with the complete corresponding
> -machine-readable source code, which must be distributed under the terms of
> -Sections 1 and 2 above on a medium customarily used for software interchange.
> -
> -If distribution of object code is made by offering access to copy from a designated
> -place, then offering equivalent access to copy the source code from the same
> -place satisfies the requirement to distribute the source code, even though
> -third parties are not compelled to copy the source along with the object code.
> -
> -5. A program that contains no derivative of any portion of the Library, but
> -is designed to work with the Library by being compiled or linked with it,
> -is called a "work that uses the Library". Such a work, in isolation, is not
> -a derivative work of the Library, and therefore falls outside the scope of
> -this License.
> -
> -However, linking a "work that uses the Library" with the Library creates an
> -executable that is a derivative of the Library (because it contains portions
> -of the Library), rather than a "work that uses the library". The executable
> -is therefore covered by this License. Section 6 states terms for distribution
> -of such executables.
> -
> -When a "work that uses the Library" uses material from a header file that
> -is part of the Library, the object code for the work may be a derivative work
> -of the Library even though the source code is not. Whether this is true is
> -especially significant if the work can be linked without the Library, or if
> -the work is itself a library. The threshold for this to be true is not precisely
> -defined by law.
> -
> -If such an object file uses only numerical parameters, data structure layouts
> -and accessors, and small macros and small inline functions (ten lines or less
> -in length), then the use of the object file is unrestricted, regardless of
> -whether it is legally a derivative work. (Executables containing this object
> -code plus portions of the Library will still fall under Section 6.)
> -
> -Otherwise, if the work is a derivative of the Library, you may distribute
> -the object code for the work under the terms of Section 6. Any executables
> -containing that work also fall under Section 6, whether or not they are linked
> -directly with the Library itself.
> -
> -6. As an exception to the Sections above, you may also combine or link a "work
> -that uses the Library" with the Library to produce a work containing portions
> -of the Library, and distribute that work under terms of your choice, provided
> -that the terms permit modification of the work for the customer's own use
> -and reverse engineering for debugging such modifications.
> -
> -You must give prominent notice with each copy of the work that the Library
> -is used in it and that the Library and its use are covered by this License.
> -You must supply a copy of this License. If the work during execution displays
> -copyright notices, you must include the copyright notice for the Library among
> -them, as well as a reference directing the user to the copy of this License.
> -Also, you must do one of these things:
> -
> -a) Accompany the work with the complete corresponding machine-readable source
> -code for the Library including whatever changes were used in the work (which
> -must be distributed under Sections 1 and 2 above); and, if the work is an
> -executable linked with the Library, with the complete machine-readable "work
> -that uses the Library", as object code and/or source code, so that the user
> -can modify the Library and then relink to produce a modified executable containing
> -the modified Library. (It is understood that the user who changes the contents
> -of definitions files in the Library will not necessarily be able to recompile
> -the application to use the modified definitions.)
> -
> -b) Use a suitable shared library mechanism for linking with the Library. A
> -suitable mechanism is one that (1) uses at run time a copy of the library
> -already present on the user's computer system, rather than copying library
> -functions into the executable, and (2) will operate properly with a modified
> -version of the library, if the user installs one, as long as the modified
> -version is interface-compatible with the version that the work was made with.
> -
> -c) Accompany the work with a written offer, valid for at least three years,
> -to give the same user the materials specified in Subsection 6a, above, for
> -a charge no more than the cost of performing this distribution.
> -
> -d) If distribution of the work is made by offering access to copy from a designated
> -place, offer equivalent access to copy the above specified materials from
> -the same place.
> -
> -e) Verify that the user has already received a copy of these materials or
> -that you have already sent this user a copy.
> -
> -For an executable, the required form of the "work that uses the Library" must
> -include any data and utility programs needed for reproducing the executable
> -from it. However, as a special exception, the materials to be distributed
> -need not include anything that is normally distributed (in either source or
> -binary form) with the major components (compiler, kernel, and so on) of the
> -operating system on which the executable runs, unless that component itself
> -accompanies the executable.
> -
> -It may happen that this requirement contradicts the license restrictions of
> -other proprietary libraries that do not normally accompany the operating system.
> -Such a contradiction means you cannot use both them and the Library together
> -in an executable that you distribute.
> -
> -7. You may place library facilities that are a work based on the Library side-by-side
> -in a single library together with other library facilities not covered by
> -this License, and distribute such a combined library, provided that the separate
> -distribution of the work based on the Library and of the other library facilities
> -is otherwise permitted, and provided that you do these two things:
> -
> -a) Accompany the combined library with a copy of the same work based on the
> -Library, uncombined with any other library facilities. This must be distributed
> -under the terms of the Sections above.
> -
> -b) Give prominent notice with the combined library of the fact that part of
> -it is a work based on the Library, and explaining where to find the accompanying
> -uncombined form of the same work.
> -
> -8. You may not copy, modify, sublicense, link with, or distribute the Library
> -except as expressly provided under this License. Any attempt otherwise to
> -copy, modify, sublicense, link with, or distribute the Library is void, and
> -will automatically terminate your rights under this License. However, parties
> -who have received copies, or rights, from you under this License will not
> -have their licenses terminated so long as such parties remain in full compliance.
> -
> -9. You are not required to accept this License, since you have not signed
> -it. However, nothing else grants you permission to modify or distribute the
> -Library or its derivative works. These actions are prohibited by law if you
> -do not accept this License. Therefore, by modifying or distributing the Library
> -(or any work based on the Library), you indicate your acceptance of this License
> -to do so, and all its terms and conditions for copying, distributing or modifying
> -the Library or works based on it.
> -
> -10. Each time you redistribute the Library (or any work based on the Library),
> -the recipient automatically receives a license from the original licensor
> -to copy, distribute, link with or modify the Library subject to these terms
> -and conditions. You may not impose any further restrictions on the recipients'
> -exercise of the rights granted herein. You are not responsible for enforcing
> -compliance by third parties with this License.
> -
> -11. If, as a consequence of a court judgment or allegation of patent infringement
> -or for any other reason (not limited to patent issues), conditions are imposed
> -on you (whether by court order, agreement or otherwise) that contradict the
> -conditions of this License, they do not excuse you from the conditions of
> -this License. If you cannot distribute so as to satisfy simultaneously your
> -obligations under this License and any other pertinent obligations, then as
> -a consequence you may not distribute the Library at all. For example, if a
> -patent license would not permit royalty-free redistribution of the Library
> -by all those who receive copies directly or indirectly through you, then the
> -only way you could satisfy both it and this License would be to refrain entirely
> -from distribution of the Library.
> -
> -If any portion of this section is held invalid or unenforceable under any
> -particular circumstance, the balance of the section is intended to apply,
> -and the section as a whole is intended to apply in other circumstances.
> -
> -It is not the purpose of this section to induce you to infringe any patents
> -or other property right claims or to contest validity of any such claims;
> -this section has the sole purpose of protecting the integrity of the free
> -software distribution system which is implemented by public license practices.
> -Many people have made generous contributions to the wide range of software
> -distributed through that system in reliance on consistent application of that
> -system; it is up to the author/donor to decide if he or she is willing to
> -distribute software through any other system and a licensee cannot impose
> -that choice.
> -
> -This section is intended to make thoroughly clear what is believed to be a
> -consequence of the rest of this License.
> -
> -12. If the distribution and/or use of the Library is restricted in certain
> -countries either by patents or by copyrighted interfaces, the original copyright
> -holder who places the Library under this License may add an explicit geographical
> -distribution limitation excluding those countries, so that distribution is
> -permitted only in or among countries not thus excluded. In such case, this
> -License incorporates the limitation as if written in the body of this License.
> -
> -13. The Free Software Foundation may publish revised and/or new versions of
> -the Lesser General Public License from time to time. Such new versions will
> -be similar in spirit to the present version, but may differ in detail to address
> -new problems or concerns.
> -
> -Each version is given a distinguishing version number. If the Library specifies
> -a version number of this License which applies to it and "any later version",
> -you have the option of following the terms and conditions either of that version
> -or of any later version published by the Free Software Foundation. If the
> -Library does not specify a license version number, you may choose any version
> -ever published by the Free Software Foundation.
> -
> -14. If you wish to incorporate parts of the Library into other free programs
> -whose distribution conditions are incompatible with these, write to the author
> -to ask for permission. For software which is copyrighted by the Free Software
> -Foundation, write to the Free Software Foundation; we sometimes make exceptions
> -for this. Our decision will be guided by the two goals of preserving the free
> -status of all derivatives of our free software and of promoting the sharing
> -and reuse of software generally.
> -
> -   NO WARRANTY
> -
> -15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
> -THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
> -STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
> -"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
> -BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
> -FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
> -OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
> -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
> -
> -16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
> -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
> -THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
> -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE

> -How to Apply These Terms to Your New Libraries
> -
> -If you develop a new library, and you want it to be of the greatest possible
