See https://cgit.freebsd.org/ports/commit/?id=b460e08f9365
mesa-dri may accidentally end up using llvm >= 16 once meson adds
'-16', '-17', etc. to the suffix list while more than one llvm* package
is installed.

To reproduce right now (with meson-0.64.1):
1. Lower pinned LLVM_DEFAULT back to 13
2. Install llvm13, llvm14, llvm15
3. Run "make clean configure"
4. Notice "llvm-version:    14.0.6"

However, meson >= 0.64 supports LLVM_CONFIG variable which allows to
avoid BINARY_ALIAS (e.g., 6df38243af67).
