Mesa: add support for intel / X11

[rhubert]

Depends on BobBuildTool/basement#236

Thanks. I was recently looking into the basic LLVM support and tried to improve upon it. It still feels a bit too hacky for such a fundamental component IMHO. I think I have some basic understanding but it still does not work as I would like to have it.

Would it be OK to flesh out the LLVM/clang support in basement first. I'm afraid it will take a bit more time. Or do you have follow-up PRs in preparation that would require to merge this PR here in the near future?

Both :) There is more to come (e.g. X-Server,...) depending on this. But there is no need to hurry...

Thanks. I had two small issues and added fixes for them:

• It was necessary to adapt bobMinimumVersion in this layer as well, since basement needs 1.1.0rc1 now. Otherwise the Parse error: Layer 'basement' requires a higher Bob version than root project! error was raised.

• Incompatible variants:

basement-gnu-linux/tests/buildall$ bob ls
Parse error: Incompatible variants of package: /buildall-x86_64/libs::mesa3d-intel-tgt/libs::zlib-tgt vs. /buildall-x86_64/devel::squashfs-tools/libs::zlib-tgt
Processing stack: buildall-x86_64
This error is caused by 'libs::zlib-tgt' that is passed upwards via 'provideDeps' from multiple dependencies of 'buildall-x86_64'.
These dependencies constitute different variants of 'libs::zlib-tgt' and can therefore not be used in 'buildall-x86_64'.
