* include/signal.h: Use libc_hidden_proto for raise, sigemptyset,
	sigfillset, sigismember, __sigpause, __libc_current_sigrtmin,
	and __libc_current_sigrtmax.
	* signal/sigismem.c: Add libc_hidden_def.
	* signal/sigfillset.c: Likewise.
	* signal/sigempty.c: Likewise.
	* sysdeps/generic/sigpause.c (__sigpause): Likewise.
	* sysdeps/posix/sigpause.c (__sigpause): Likewise.
	* sysdeps/unix/bsd/osf/alpha/sigpause.S: Likewise.
