x86 darwin should be able to re-use the implementation from
rs6000/driver-rs6000.c because the kernel interfaces to query the information
are the same.

Well and i386/driver-i386.c uses inline-asm so it should able to use that also.
EXTRA_GCC_OBJS =driver-i386.o darwin-driver.o
We are able to compile driver-i386.c but just not use it.

The problem is that CC1_SPEC does not use %(cc1_cpu).

Thanks,
Andrew Pinski

Fixed (I added a space after %(cc1_cpu) for the final patch).
