* elfcode.h (elf_map_symbols): Don't worry about section symbols
in a section not owned by any BFD. (elf_section_from_bfd_section): Separate out loop which calls backend routine. Check bfd_section and call the backend routine even for a section not owned by any BFD. * elf32-mips.c (mips_elf_section_from_bfd_section): Handle .acommon section.
