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. * sysdeps/generic/dl-sysdep.c: Initialize _dl_cpuclock_offset to move it into data section.
