Update.
	* sysdeps/ia64/Makefile [subdir=csu] (sysdep_routines): Add hp-timing.
	* sysdeps/ia64/Versions: Add _dl_cpuclock_offset for ld in 2.2.3.
	* sysdeps/ia64/hp-timing.c: New file.
	* sysdeps/ia64/hp-timing.h: New file.
	* sysdeps/unix/sysv/linux/ia64/bits/time.h: Add definitions for
	CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID.

	* sysdeps/generic/clock_getcpuclockid.c: Make function generic, test
	using #ifdef whether the clock is available.
	* sysdeps/unix/i386/clock_getcpuclockid.c: Not needed anymore.
