* elf32-ppc.c (ppc_elf_check_relocs): Always add a plt ref count

	* elf32-ppc.c (ppc_elf_check_relocs): Always add a plt ref count
	for local ifunc symbols in non-pie executables, regardless of
	reloc type.  Don't specially create ifunc dyn relocs.  Tidy ifunc
	code so that it's obvious that we only do anything special for
	local ifunc syms.
	(ppc_elf_gc_sweep_hook): Adjust to suit check_relocs changes.
	(allocate_dynrelocs): Correct comment for syms defined in plt.
	Don't specially allocate ifunc dyn relocs.
	(ppc_elf_relax_section): Relax branches to ifunc plt entries too.
	(ppc_elf_relocate_section): Set "relocation" value for ifunc
	syms in non-pie executables.  No specially allocated dyn relocs
	for ifunc to write.  Allow for local sym on R_PPC_RELAX32_PLT.
	(ppc_elf_finish_dynamic_symbol): Set value of ifunc symbols in
	a non-pie executable.
