Fix sigwait namespace (bug 21550).
sigwait was added to POSIX in 1995; it is not in older POSIX versions or XPG4 / XPG4.2. Thus it should be declared only if __USE_POSIX199506; signal.h wrongly declares it for __USE_POSIX. (sigwaitinfo is correctly conditioned on __USE_POSIX199309.) This patch fixes the condition on the declaration of sigwait. Tested for x86_64. Because of other namespace problems this does not allow any conform/ XFAILs to be removed. [BZ #21550] * signal/signal.h (sigwait): Only declare if [__USE_POSIX199506].
