The install prefix in such a case is the qtbase build dir, and not the qt6 top-level build dir. This caused issues with certain incorrect paths being generated, including a broken qt-cmake-standalone-test script, as well as upon reconfiguration determining that a non-prefix build should be installed. The fix for a non-prefix build is to check explicitly for the qtbase build dir. This works both for super and non-super builds.
