[I think brooks answered the others.]

You can use the 'beforebuild' target to trigger that.

If however the src generation is non-trvial and especially if you need
to build them for multiple arch, it is better to do the generation in a
separate dir (eg subdir like gen/) so that it is easy to do the
generation once only.

Separate dirs make build orchestration simpler.
