Update.

	* sysdeps/powerpc/powerpc64/dl-machine.h
	(elf_machine_runtime_setup): If profile != 0 does not anymore mean
	GLRO(dl_profile) != NULL.
	* sysdeps/powerpc/powerpc64/bits/link.h (struct la_ppc64_regs): Add
	padding.
	* sysdeps/powerpc/powerpc64/dl-trampoline.S: (_dl_profile_resolve):
	Extend _dl_prof_resolve to add pass extra parameters to
	_dl_profile_fixup and set up structure with register content.
