* elf/dl-close.c: Include <string.h> for memcpy.
* elf/dl-lookup.c: Same.
* elf/elf.h: Add Elfxx_Symndx for symbol indices.
* elf/dl-lookup.c (_dl_lookup_symbol): Use it.
(_dl_setup_hash): Use it.
* elf/link.h (struct link_map): Use it.
* elf/rtld.c (_dl_start): Don't rely on pointer-to-first-arg hack
for getting the argc/argv/envp block. Instead, make it the argument.
sysdeps/i386/dl-machine.h (RTLD_START): Do that.
sysdeps/m68k/dl-machine.h (RTLD_START): Same.
* shlib-versions: Add version numbers for alpha-linux. To avoid
user confusion, make them the same as i386-linux.
* sysdeps/alpha/Makefile [subdir elf]: Add -mno-fp-regs to
sysdep-CFLAGS so that _dl_runtime_resolve doesn't have to save them.
Add -mbuild-constants to CFLAGS-rtld.c to that we can bootstrap
without using literal data.
* sysdeps/generic/dl-sysdep.c: Include <string.h> for memcpy.
Finish Elf32 -> ElfW migration.
