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.
