gle-graphics FTBFS on armel and armhf:

...
3dviewer.cpp: In destructor ‘virtual QGLE3DWidget::~QGLE3DWidget()’:
3dviewer.cpp:56:6: error: ‘glDeleteLists’ was not declared in this scope
   56 |      glDeleteLists(object, 1);
      |      ^~~~~~~~~~~~~

The root cause is that on armel/armhf
Qt5 is compiled with OpenGL ES instead of OpenGL.

Ideally it should be fixed to build and work with OpenGL ES,
changing the build dependency from libqt5opengl5-dev to
libqt5opengl5-desktop-dev would at least stop trying to
build on armel/armhf.
