Nearly no linux platform uses this file since it's too x86 specific.
Actually I believe not even most of the *_SPEC defines belong in there,
they differ too much across all the linux targets.
On the patch itself, how can "-D_GNU_SOURCE %(cpp_cpu)" be correct?
Shouldn't that be %(cpp)? At least on PPC I have to use %(cpp), because
otherwise c++ won't get -D__BIG_ENDIAN__ (preventing compilation of
libstdc++) etc. and things like -posix, -pthread, -fpic/-fPIC won't produce
the proper defines _POSIX_SOURCE, _REENTRANT and __pic__/__PIC__.
