Don't sort ld -r relocs for mips
HI16/LO16 are deliberately put adjacent, which might mean relocs are
then not sorted by r_offset. See tc-mips.c:mips_frob_file. Don't undo
the HI16/LO16 sorting.
PR 17666

(elfNN_bed): Init new field.
* elflink.c (elf_link_adjust_relocs): Conditionally sort.
(bfd_elf_final_link): Control sorting of relocs.
* elfxx-mips.c (_bfd_mips_elf_sort_relocs_p): New function.
* elfxx-mips.h (_bfd_mips_elf_sort_relocs_p): Declare.
* elf32-mips.c (elf_backend_sort_relocs_p): Define.
