Update.

	* sysdeps/unix/sysv/linux/i386/i486/lowlevelmutex.S: Don't define
	LOCK is already defined.  Don't define __lll_mutex_timedlock_wait
	for libc.so.
	* sysdeps/unix/sysv/linux/i386/i486/libc-lowlevelmutex.S: Only
	define LOCK here (if UP is not defined).  The actual code is in
	lowlevelmutex.S.
