Disable x87 inline functions for SSE2 math
When i386 and x86-64 mathinline.h was merged into a single mathinline.h, "gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse and SSE2 is enabled. It is a regression on x86-64. We should check __SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions.
