ia64: initfini.c -> crt{i,n}.S split
This was done mostly by looking at the processed crt{i,n}.S files in glibc-2.15, and then added the required update for using in either csu/ or nptl/. Seems to work -- when an earlier version didn't call the initializers, many tests (pthread related) failed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
