Well, the linker can't guarantee to fix up the reference to point to
the proper location in the kept section. Just considering the linker
in isolation, I think it warrants an error. However, I thought this
gcc bug had been fixed long ago, but if this is occurring with 4.0.2,
perhaps we ought to downgrade the error to a warning again. (I'm
assuming that the reference was from C++ code rather than assembly,
and that your .a was actually compiled with 4.0.2)

Pass --noinhibit-exec to the linker.
