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.
