* elf-bfd.h (struct elf_backend_data): Reorder collect and
type_change_ok; add sign_extend_vma.
* elf32-mips.c (elf_backend_sign_extend_vma): Define.
* elfcode.h (elf_swap_symbol_in): Mind be->sign_extend_vma.
(elf_swap_shdr_in, elf_swap_phdr_in): Likewise.
* elfxx-target.h (elf_backend_sign_extend_vma): Default.
(elfNN_bed): Follow struture changes.
