This is especially needed for obj-pbl-y code as the files usually have other functions depending on barebox proper infrastructure, but that is never called. This works so far, but breaks for two things: LTO and using PBL on sandbox. Both I have not managed to get the linker not to complain about the undefined references in the ultimately unreferenced code. Therefore, let's solve this a different way: Add an IS_PROPER macro and have the stubs defined when !IS_PROPER. This has the nice side effect of compile testing the stubs during PBL build, so forgotten semicolons are more likely to be noticed during development instead of CI run.
