* elflink.h (elf_link_add_object_symbols): Optimize stabs for
relocatable link too.
(elf_link_input_bfd): When emitting relocs, adjust offsets for
eh_frame and stab sections. Zap deleted relocs.
(elf_reloc_symbol_deleted_p): Return true for zero r_symndx.
(elf_bfd_discard_info): Run for relocatable link too.
* elf64-ppc.c (ppc64_elf_edit_opd): Rename from edit_opd. Make global.
Handle ld -r case.
(ppc64_elf_size_dynamic_sections): Don't call edit_opd from here.
* elf64-ppc.h (ppc64_elf_edit_opd): Declare.
