On mips, what should happen if you give -mips3 on the command line?
Should it override the default -march?  Seems like the default would
win as things stand.

I suppose you could have:

  if (!option_present (*argcp, *argvp, "-march=")
      && (!option_present (*argcp, *argvp, "-mips")
          || option_present (*argcp, *argvp, "-mips16")))
    add_option (argcp, argvp, "-march=" XSTRING (TARGET_DEFAULT_OPTION_ARCH));

(since -mips16 shouldn't change the default arch) but maybe
there needs to be some sort of target macro?
