Make fallback fegetexceptflag work with generic fetestexceptflag.
The generic implementation of fetestexceptflag does: int fetestexceptflag (const fexcept_t *flagp, int excepts) { /* Most versions of fegetexceptflag store exceptions in a form such that this works. */ return *flagp & excepts & FE_ALL_EXCEPT; } In the case where FE_ALL_EXCEPT is nonzero but exceptions may not be supported at runtime, this only works if fegetexceptflag cleared all the bits of FE_ALL_EXCEPT in *flagp; otherwise it accesses uninitialized data. This showed up as a failure of math/test-fetestexceptflag for MIPS o32 soft-float. This patch makes the fallback fegetexceptflag store 0 (fexcept_t is an integer type everywhere) so that this works. (No bug report in Bugzilla because this wasn't user-visible - at least, without using tools to detect uninitialized memory use at runtime - without fetestexceptflag, which is new in 2.25.) Tested for MIPS o32 soft-float. * math/fgetexcptflg.c (__fegetexceptflag): Store 0 in fexcept_t object.
