I also updated curl as it was going to be rebuilt and had a new
version out (with some security fixes). I hadn't grafted it on master
but we could do that if the mesa-updates branch isn't merged to master
first.

I also had to skip a failing test (unknown reasons) of gtk with these
updates.

Finally, I also enabled the zink driver in Mesa (zink is for OpenGL on
Vulkan). I remember someone asking about it on #guix recently as well,
and we should have it enabled in general, to support devices which may
not be able to use OpenGL without it.

This is still true though I've tried to manually restart lots of
builds on x86_64 and i686, which has removed many of the failures. Any
idea what is happening to cause this more recently?

I haven't seen QA process this branch, so I'm just going with what I
see on Berlin. From the branches overview it shows about 61% last I
saw, compared to 72% for master. Unfortunately, non x86 architectures
are usually better covered by Bordeaux, but I don't know where to get
a sense of that coverage. For what it is worth, Efraim has manually
built xorgproto and mesa at least on powerpc64le, riscv64, without
issues.

Coverage on x86_64 and i686 seems good from what I can tell. I also
don't think there are any other branches ready to merge, and would
like to give them time to rebuild once these changes hit.

Any thoughts on when to merge?

Thanks everyone!
