Mark fegetround pure (bug 16296).
Bug 16296 notes that fegetround is a pure function and should be marked as such in fenv.h. This patch implements that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by this patch). [BZ #16296] * math/fenv.h (fegetround): Use __attribute_pure__. * include/fenv.h (__fegetround): Likewise.
