The multi-profile stuff is something we want to have for all targets, so
that we can avoid hackish scripts involving the image builder and
multiple build passes.
Converting ar71xx is going to be a lot of work, especially testing all
those different devices - unless you can find a way to automate that by
proving that the output stays the same with the old and the new code,
but I don't know if our reproducible build support is quite there yet.
