* config/tc-mips.c (mips_64): New static variable.
(mips_target_format): If mips_64, return elf64 targets rather than elf32 ones. (md_longopts): Add "32" and "64". (md_parse_option): Handle -32 and -64. (md_show_usage): Mention -32 and -64. (cons_fix_new_mips): If mips_64, don't convert an 8 byte reloc to a 4 byte one.
