* elfxx-mips.c (mips_elf_link_hash_table.rld_value): Remove. (mips_elf_link_hash_table.rld_symbol): New field; (MIPS_ELF_RLD_MAP_SIZE): New macro. (_bfd_mips_elf_add_symbol_hook): Remember __rld_obj_head symbol in rld_symbol. (_bfd_mips_elf_create_dynamic_sections): Remember __rld_map symbol in rld_symbol. (_bfd_mips_elf_size_dynamic_sections): Set correct size for .rld_map. (_bfd_mips_elf_finish_dynamic_symbol): Remove .rld_map handling. (_bfd_mips_elf_finish_dynamic_sections): Use rld_symbol to calculate DT_MIPS_RLD_MAP value. (_bfd_mips_elf_link_hash_table_create): Initialize rld_symbol, quit initializing rld_value.
