The proliferation of special switches makes me nervous as the testing matrix
gets larger and larger. We already run into this with system vs custom
compiler regularly. I agree that we should look into the compiler-as-a-package
design and figure out if there's a general way to specify paths to OPAM
endpoints like %{bindir} as part of that.
