* elf64-ppc.c (struct ppc_link_hash_table): Reinstate top_index.

	Restore previous input_list type.
	(ppc64_elf_link_hash_table_create): Undo last change.
	(ppc64_elf_setup_section_lists): Reinstate code setting up input lists
	per output section, but don't bother with bfd_abs_section marker.
	(ppc64_elf_next_input_section): Adjust for multiple input section
	lists.
	(group_sections): Likewise.
