* elflink.c (_bfd_elf_adjust_dynamic_symbol): Don't clear plt

	info for STT_GNU_IFUNC.
	* elf32-ppc.c (ppc_elf_check_relocs): Count a needed plt entry
	on got refs in case the symbol turns out to be ifunc.
	(ppc_elf_gc_sweep_hook): Similarly.
	(ppc_elf_adjust_dynamic_symbol): Adjust assertion.
	(allocate_dynrelocs): Don't specially allocate got relocs for ifunc.
	(ppc_elf_size_dynamic_sections): Likewise.
	(ppc_elf_relocate_section): Likewise.
