It's unlikely to convince the Qt5 maintainers to change something just 
to support last century's technology (and therefore probably be unable 
to draw full power out of todays technology).

But if all that kodi did is linking against libGL instead of (the 
subset) libGLX, maybe we can just replace libGLX.so.1 with a link to 
libGL.so.1 s.t. we always end in the same implementation regardless of 
the entry point being used ...

Could you try

   ln -sf libGL.so.1 /usr/lib/x86_64-linux-gnu/libGLX.so.0

(assuming amd64) and see if that fixes Qt5 operation? Or breaks other stuff?

Note: this change is only active until you install/upgrade some package, 
i.e. something runs ldconfig. (You can also run ldconfig manually to 
restore the original link.)
