[PATCH] gold: Get linkonce/comdate sections for debugging sections

[H.J. Lu]

Sized_relobj_file::map_to_kept_section is used only for relocations in
debugging sections.  Get the section index for linkonce section and 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.
