	* sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S:
	Implement clock selection.
	* sysdeps/pthread/pthread_cond_timedwait.c: Likewise.
	* pthread-errnos.sym: Add ENOSYS.
	* sysdeps/unix/sysv/linux/bits/posix_opt.h: Define
	_POSIX_CLOCK_SELECTION.
	* sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.
