Because the same compile process works now, I suspect that wasn't build
failure.

I now compiled same stack, but reverted mesa to

    intel: make CopyTex[Sub]Image fallback debug messages more
consistent



And compiled the xserver with --disable-aiglx 
(I will always use that option from now on, because I hate the way X and
mesa are tied otherwise. For example X won't build if I compile it
against old mesa, etc...)

And now all 3D problems are gone.

I now doing a bisect, although I am not sure if it will help much.
