For building QEMU, yes.

The firmware submodules would not be affected, but those are really
just a way to ensure we respect the GPL when distributing firmware
blobs. We could keep them, as they mostly stay out of the way, or we
could move the information to files that are then consulted by
scripts/make-release. And those files could very well reuse the same
".ini" format that is used by .wrap files.
