Yep, or unpack the tarball and apply the patch then build with the
same configure options as you find in the rpm spec. That can be easier
when iterating tests and builds.

Since the patches are separate, you can skip the tarball and clone the
same tag from git instead. Then apply the rpm patches as separate
commits. That's typically what I'll do, makes it easier to keep track.
