Alan Modra f02571c5d9 * elflink.c (elf_link_input_bfd): Don't use linker_mark and
SEC_EXCLUDE to test for sections dropped from output.  Instead,
	use bfd_section_removed_from_list on normal sections.  Don't
	attempt to handle symbols with unknown reserved section indices.
	* linker.c (_bfd_generic_link_output_symbols): Don't use
	linker_mark to test for symbols belonging to dropped sections.
	Do allow absolute symbols.
