config.gcc arranges for vxworks 7r2+ targets to include linux.h,
because of the similarity, but linux.h defines
TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL to a function declared in
linux-protos.h, and defined in linux.cc, neither of which vxworks
targets include. Undefine it in vxworks.h.
Tested with gcc-14 targeting ppc-vx7r2 and ppc64-vx7r2. Also tested
with trunk on ppc64le-linux-gnu, and with gcc-14 targeting powerpc-elf.
Ok to install?

* config/vxworks.h (TARGET_FORTIFY_SOURCE_DEFAULT_LEVEL):
Undefine.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
