* elflink.c (_bfd_elf_gc_mark): Mark sections referenced by
.eh_frame specially..
(bfd_elf_gc_sections): ..rather than totally ignoring .eh_frame.
Don't recheck sections we have already marked.
(elf_gc_sweep): Keep non-code sections referenced from .eh_frame.
* section.c (struct bfd_section): Add gc_mark_from_eh.
(STD_SECTION): Adjust.
* ecoff.c (bfd_debug_section): Adjust.
* bfd-in2.h: Regenerate.
