Thanks.  This is awesome (and long needed!) work.

I'd suggest, if possible, you try to upstream your patches, as you are 
likely to get more knowledgable review there, but we'll try to take a 
look at them...

I would like to ask why you've dropped debuginfo package generation, and 
why LLVM_CONFIG_PATH needs explicitly setting, in most packages?
