Now, instead of doing the sane thing (dropping the configure argument) or submitting a useful patch, the problem was just wallpapered over by adding another override-of-override hidden in packaging... That said, the overriding power of the configure flag against UNAME_MINIMUM_RELEASE is probably not very useful. We might want to drop the configure flag, and set an UNAME_MINIMUM_RELEASE for all targets. For people who still want to override, keep the enviroment variable setting available.
