Temporarily disabled, because the postmarketOS binary repository has
armhf packages for various kde related packages depending on
qt5-qtwebengine-dev, although qt5-qtwebengine-dev isn't available for
armhf anymore. All related pmaports were disabled for armhf, however
currently the binary repository does not delete binary packages yet,
after the corresponding pmaport was deleted/disabled for a given arch.
I'll work on this with high priority, so we can enable the test again.
