New Issue: problem finding installed LLVM on alpine linux

19404, "mppf", "problem finding installed LLVM on alpine linux", "2022-03-09T21:19:57Z"

On alpine linux 314, the clang-dev package installs the clang headers to e.g. usr/include/clang/Frontend/ASTUnit.h but our scripts end up looking in a path based on llvm-config --include e.g. /usr/lib/llvm11/include/clang/Basic/Version.h.

I think we could resolve the problem by updating our scripts to look in /usr/include/clang.
