Subject:         * 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.
