improve llvm version picking

Browse Source 
In arch, the `llvm` package points to the latest version of LLVM, this
installs `llvm-config` but not a `llvm-config-21` link. This meant that
we would check all our lower supported versions before falling back to
the default `llvm-config`.

This change makes sure that if `llvm-config` exists we check against the
major version (by using `llvm-config --version`) and make sure we have
the highest llvm version we support.
