`stack setup` should not be called inside `nix-build` because that makes stack download a GHC instead of using nix's one (the one provided `generic-stack-builder.nix` as the `ghc` argument), which will not work. Further evidence for this is that the `stack --nix` support intentionally uses `--system-ghc` for the same purpose.
