I was misreading your patch :)

At any rate, it doesn't look backwards compatible.
You'll need to make sure that the case where -mcpu
is given, but -march is not is handled with -mcpu
setting the default architecture for the assembler.

You may want to issue a warning that this behavior
is deprecated though so that we can remove it in a
future version.

Sound ok?
