Fix --as-needed undefined symbol references from dynamic libraries.

libx.so refers to some_sym, liby.so provides some_sym@some_version
wasn't seen as satisfying the reference.

	* elf64-ppc.c (_bfd_elf_add_default_symbol): Set dynamic_def
	and ref_dynamic_nonweak when chaining together indirect
	symbols.
