Have you tried LLVM_CONFIG, does it not work on your setup?
Alternatively can you update the your scripts, I can provide a patch
if you prefer.

Even Debian (which I personally consider fairly conservative) has been
using it for a minimum of two years.

years, it will work for any Mesa checkout since its inception.
You can safely bisect Mesa and things will just work.
