MIPS: Fix GCC-4.6 'set but not used' warning in ieee754int.h



GCC-4.6 can find more unused code than previous versions could.

In the case of arch/mips/math-emu/ieee754int.h, the COMPXSP and
COMPXDP macros are used in several places, but a couple of them leave
xs unused.  The easiest thing to do is mark it as __maybe_unused to
quiet the warning.
