* elf32-mips.c (mips_elf_add_symbol_hook): Don't set the owner of
the magic sections used for SHN_MIPS_TEXT and SHN_MIPS_DATA. Don't return bfd_und_section_ptr when info->shared. (mips_elf_final_link): Set the alignment of .rtproc to 4, not 12. (mips_elf_create_dynamic_sections): Correct type: ^= for &=. (mips_elf_check_relocs): Resolve an indirect symbol in sym_hashes. (mips_elf_finish_dynamic_symbol): Don't change SHN_ABS into SHN_MIPS_TEXT or SHN_MIPS_DATA.
