Define __NO_MATH_INLINES on linux/x86 so that we don't get inline

functions in glibc header files that use FP Stack inline asm which the
backend can't deal with (PR879).

This "fixes" PR3970 for linux.  Other affected systems should do similar
things.  Maybe this should just go to the general i386/x86-64 sections?
