This comes from upstream and will change with the release:

https://github.com/llvm/llvm-project/commit/22683463740e55e7e0d7e664395c30899b229205

I wonder if mesa is inappropriately hard coding the library name or if
there's a cmake file issue that should be resolved upstream (those
generally seem to reference static libs though).

$ llvm-config18 --libs
-lLLVM-18rc
