	* elf/dl-support.c: Include cpuclock-init.h.  Use CPUCLOCK_VARDEF and
	CPUCLOCK_INIT if defined.
	* sysdeps/generic/dl-sysdep.c: Likewise.
	* sysdeps/generic/cpuclock-init.h: New file.
	* sysdeps/unix/i386/i586/cpuclock-init.h: New file.
	* sysdeps/unix/i386/i586/Versions: New file.
	* sysdeps/unix/i386/i586/clock_settime.c: New file.
	* sysdeps/unix/i386/i586/clock_gettime.c: Handle thread CPU clock
	separately by calling __pthread_clock_gettime if this function is
	available.  Subtract offset from tsc value before computing time value.
