because qtractor is not really intended to be strictly compiled with
qt4. it can be compiled to qt5 as well, only that the former is still
the recommended way (as is the default on configure).

one other problem is that the possible values for QT_SELECT might not be
so simple as either "4" or "5" (is it?). it probably depends on what you
have installed and whether it's provided and available on your distro.
for instance, my distro (opensuse) has no such thing, maybe just yet.
qtchooser doesn't even come with the official/stock/vanilla qt5 binary
packaging (as from qt-project.org and qt.io) which are the ones i've
been testing my qt5 builds. maybe it's considered an extra, an ad-hoc
utility, targeted to distro packagers... i can't really tell.
