hg: panama/dev: Summary: Add libclang version check and option to select version

[Maurizio Cimadamore]

I think that was the goal yes, to prevent you from using versions that 
are not working fully with jextract.

In reality I had no trouble with LLVM 4/5/6 - but the logic Jorn 
submitted is simpler, and it's clear what you have to do in order to get 
started. If you really want to override, you have the option to do so 
(at your own risk), which is also good.
