Thanks a lot for your help!

I am still trying to give you the requested info as soon as possible but I ran
into several issues trying to compile Mesa and I am also a bit busy sometimes.
However, I know how to fix the remaining issues and it will just be a matter of
time to fix the whole string to the end. It's also pretty educational.

But I would also be happy when someone who owns this game and compiles Mesa
regularly could test this patch on his own to accelerate the procedure.

The only thing I could find out so far was that it also crashes with 17.0.3
which is the standard version of Ubuntu 17.04 and it also runs fine while the
shaders are dumped.
