PATCH: macro redefinition warning axe

[Loren James Rittle]

David, are you OK with this patch for mainline?

It removes ~1000 useless redefinition warnings while bootstrapping
alpha-*-freebsd* since config/alpha/elf.h uses the latter style (I
will not ask the obvious question: ``what does ELF format support have
to do with accepting #sccs''? ;-).  OTOH, perhaps the preprocessor
should not report the case where a macro defined to be '1' explicitly
is redefined to be '1' implicitly or vice versa.  Opinions?
