Qt5 in Debian is configured to use OpenGL ES instead of OpenGL
on 32-bit arm, and this causes problems with packages that also
try to use OpenGL directly (see #798408).

The libqt5opengl5-desktop-dev provides was added for that,
build depending on libqt5opengl5-desktop-dev instead of
libqt5opengl5-dev would prevent attempting to build on armhf.
