Not related to this PR, but I'd like to raise the question here:
For configurable cores, what is the best way to specify the features? `-mcpu`
is meant to support the base configuration, but how can we specify the
additional optional extensions? Apparently, failing back to `-march` is silly.
My thought is: can we support `-march/-mcpu` where the values can be
`{cpu}(_ext)*`? Will such use be problematic?
