PowerPC fix for ifunc broken by d1eca1e4 

This probably could be fixed by making changes in relocate_section for
ifunc, but it's simpler to disable the optimisation for ifunc.

	* elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Don't attempt to
	use dynrelocs for ifunc.
	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Similarly.
