Thanks! Initially I added dri-devel, since mesa-dev looked rather dead in
comparison to dri-devel. Also the issue was initially Intel driver specific.

Thanks, I will split this up and apply this one only for systems with python
3.6.

Yeah. We'll see, what the feedback will be. Obviously Mesa is no longer
build-tested with python 3.6, so I may end up fighing against windmills
anyway, I will try to request a newer pyhton for next enterprise service pack
product, but I'm afraid it will be rejected. :-(

Unfortunately it's likely I also need a python 3.6 supported Mesa also beyond
23.3.x. :-( See my previous comment.

For now I will give the patches a try for our Betas and a few weeks from now I
will try to make a pull request for my changes. Hope this makes sense.

Thanks,
Stefan
