[IA64] Turn on CONFIG_HAVE_UNSTABLE_CLOCK
sched_clock() on ia64 is based on ar.itc, so is never completely synchronized between cpus. On some platforms (e.g. certain models of SGI Altix) it may be running at radically different frequencies. Based on a patch from Dimitri Sivanich which set this just for SN2 && GENERIC kernels ... it is needed for all ia64 machines. Signed-off-by: Tony Luck <tony.luck@intel.com>
