Each version of adwaita-qt will install a single file IIRC, that file
being /usr/lib/qt/plugins/styles/adwaita.so

Thus, logically, one cannot install both the Qt4 and Qt5 versions
simultaneously, because the packages will error out with a conflicting
files message.

The solution is simple, and in accordance with long-standing package
policy, adwaita-qt is the "main" package, and all other packages must
provide/conflict against it. For more details, see:
https://wiki.archlinux.org/index.php/PKGBUILD#conflicts

The adwaita-qt5 name is different, since it is what this package used to
be called, and if anyone depends on "adwaita-qt5" which does not exist,
this package must provide that dependency.

(Some people might argue that the package should be called adwaita-qt5
anyway. It would match the naming for other qt5-* packages then.)
