my src is f9df22b002af99532b66360e08128e

now config it:
    CROSS_COMPILE= ARCH=sandbox make sandbox_defconfig

Then add the the flowwing line in front of include/common.h

    #define DEBUG

and run "CROSS_COMPILE= ARCH=sandbox make", this command output
the flowwing message:

--------------------------------------
  CC      common/meminfo.o
common/meminfo.c: In function 'display_meminfo':
common/meminfo.c:12:49: error: '_stext' undeclared (first use in this function)
common/meminfo.c:12:49: note: each undeclared identifier is reported only once for each function it appears in
common/meminfo.c:12:57: error: '_etext' undeclared (first use in this function)

make[1]: *** [common/meminfo.o] Error 1
make: *** [common] Error 2
--------------------------------------

is this a bug?

This is because ./arch/sandbox/board/barebox.lds.S is missing these
variables. I don't know how much sense it makes to add these. You could
just try and add them as done in the other linker scripts.

This is a bug in the sense that you should be able to compile with DEBUG
defined, but otherwise you can just comment the lines out and ignore
this. It will have no bad effect on the resulting binary.

on sandbox we should ignore this as the lds is based on the gcc one
and we just insert section inside
