Subject: 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

	section index for linkonce section.  Also check the single
