Note that -march=foo without any -mtune= implies -mtune=, so either
the assembler needs to be passed -march= too (provided that -march=foo
and no -mtune= for as implies -mtune=foo), or the spec changes would need to
be smarter.  Also I believe you'd need configure to check for what
-mtune= arguments to as are accepted.
