libglvnd git is now updated, have a look.. It's split again since
there's no way to avoid that.

I have a weird issue bootstrapping mesa, where rebuilding it fails to
install libva-dev, which pulls in some bits of the previously built mesa
which depend on libglvnd. I hope it's just not using my local repo
properly..
