* elf64-ppc.c (ppc64_elf_edit_opd): Support 16 byte long .opd
entries (where fd_aux overlaps next entry's fd_func).
Add non_overlapping argument, use it.
(ppc64_elf_check_relocs, ppc64_elf_gc_mark_hook, adjust_opd_syms,
ppc64_elf_size_stubs, ppc64_elf_relocate_section,
ppc64_elf_output_symbol_hook): Use address / 8 instead of address / 24
as indexes into opd_sym_map/opd_adjust array.
* elf64-ppc.h (ppc64_elf_edit_opd): Adjust prototype.
* emultempl/ppc64elf.em (non_overlapping_opd): New variable.
(ppc_before_allocation): Pass it to ppc64_elf_edit_opd).
(OPTION_NON_OVERLAPPING_OPD): Define.
(PARSE_AND_LIST_OPTIONS, PARSE_AND_LIST_ARGS_CASES): Add
--non-overlapping-opd option.
