gold: Get linkonce/comdate sections for debugging sections
When relocating debug sections, get the section index for the linkonce
section. Since symbols referenced in debugging sections can be defined
a single comdat section with a different section name, also check the
single comdat section.
PR gold/26937
* object.cc (Sized_relobj_file::map_to_kept_section): Get the
section index for linkonce section. Also check the single
comdat section.
