* config/tc-mips.c (mips_64): New static variable.

Browse Source 
(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.
