What does the "it" in "does it work" mean here? If you mean the
builds themselves, then no. Success isn't guaranteed because the
configure scripts might not be patched, as the patching phases are
finished before the "build" phases. This change ensures that the
"patch-usr-bin-file" phase can operate on generated configure scripts if
necessary:

I agree. It would cut down on repetitive, common code and potential for
"autoreconf-ing" incorrectly.
