Update.
2001-08-24  Ulrich Drepper  <drepper@redhat.com>

	* elf/do-rel.h (elf_dynamic_do_rel): If not relocating lazily, don't
	call elf_machine_rel for the last DT_RELCOUNT relocations but instead
	elf_machine_rel_relative.
	* sysdeps/alpha/dl-machine.h: Define elf_machine_rel_relative.
	Minor optimizations.
	* sysdeps/arm/dl-machine.h: Likewise.
