Update.

* elf/dl-lookup.c (_dl_num_relocations): New variable.
(do_lookup): Increment _dl_num_relocations for every call.
* elf/rtld.c (print_statistics): New function.
(_dl_debug_statistics): New variable. Set when statistics are asked
for.
(rtld_total_time, relocate_time, load_time): New variables. Used
in print_statistics.
(_dl_start): Record start and end time of startup. Call
print_statistics if needed.
(dk_main): Record times for relocations and loading.
(process_dl_debug): Recognize statistics.
Low-level, low-overhead, high-precision timing funcationality.
* sysdeps/generic/hp-timing.h: New file.
* sysdeps/i386/i686/Makefile: New file.
* sysdeps/i386/i686/hp-timing.h: New file.
* sysdeps/i386/i686/hp-timing.c: New file.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Reverse order of OR
clauses to avoid accessing global variables during rtld relocation.
* sunrpc/rpc_main.c: Unify messages.
* sysdeps/unix/sysv/linux/arm/Dist: Add ioperm.c and sys/io.h.
