* linker.c (_bfd_nearby_section): New function, split out from..

	(fix_syms): ..here.
	* bfd-in.h (_bfd_nearby_section): Declare.
	* bfd-in2.h: Regenerate.
	* elflink.c (elf_link_input_bfd): Don't use text_index_section or
	data_index_section with ld -q or ld -r output relocs against
	stripped output sections.  Instead use _bfd_nearby_section.
