* 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.
