I don't mind having all 3 llvm versions in parallel until all this is
sorted out.

People can select the right one based on mesa version they are using and
3.8 for OpenJDK.

But I would appreciate this recipe rebased on top of Philip's (or vice
versa), because I don't have spare time to text it with newer mesa
Philip is using or with OpenJDK Jens is using.
