4857 symbol on GOT relocs. Rearrange test for emitting GOT relocs

4862 (ensure_undefweak_dynamic): New function.
4863 (allocate_dynrelocs): Use it here. Only make undef weak symbols
4864 with GOT entries dynamic. Remove unnecessary test of
4865 WILL_CALL_FINISH_DYNAMIC_SYMBOL in PLT handling.
4866 (ppc64_elf_relocate_section): Correct test for using dynamic
4867 symbol on GOT relocs. Rearrange test for emitting GOT relocs
4868 to suit. Set up explicit tls_index entries and implicit GOT
