* elf32-mips.c: Extensive changes for a start at dynamic linking
support, from Kazumoto Kojima <kkojima@info.kanagawa-u.ac.jp>.
* elf-bfd.h (struct elf_backend_data): Add type_change_ok field.
(struct elf_backend_data): Remove
elf_backend_create_program_headers field. Add
elf_backend_additional_program_headers and
elf_backend_modify_segment_map fields.
* elfxx-target.h (elf_backend_type_change_ok): Define if not
defined.
(elf_backend_additional_program_headers): Likewise.
(elf_backend_modify_segment_map): Likewise.
(elf_backend_create_program_headers): Don't define.
(elfNN_bed): Change to account for field changes.
* elf.c (assign_file_positions_for_segments): Call new
modify_segment_map backend function. Don't call old
create_program_headers backend function.
(get_program_header_size): Call additional_program_headers rather
than create_program_headers.
* elflink.h (elf_link_add_object_symbols): Initialize
type_change_ok from new backend field.
(elf_link_output_extsym): Don't warn if _rld_new_interface is
defined.
(elf_reloc_link_order): Treat a reloc against a defined symbol as
a reloc against the appropriate section.
