Ok, well you can fix that in the gnumach makefiles.  Some of the C code
needs -Di386, but the .defs certainly don't.  Off hand it looks like the
.defs files really only need -DMACH_KERNEL and maybe a few other ones, but
not all of $(DEFINES).  Go ahead and diddle MIGFLAGS in Makefile.in however
works best.  I will put -undef into mig, but you can just put it in
MIGFLAGS too I think.
