Building this as part of a djgpp cross-toolchain fails:

collect2: ld returned 1 exit status
make[4]: *** [as-new] Error 1

This is because coff_64k_relocation_enabled is in init.c, __DJGPP__ is
not defined (because this is a cross build), nor are COFF_GO32* defined
not as far as init.c knows, as those are defined only in coff-go32.c and
init.c cannot know such a thing.  I do not have a patch for fixing this
mess, yet.
