Peter Simons b1169e5509 ghc-*-binary: remove redundant assertion
Any attempt to instantiate these expressions on an unsupported platform is
going to 'throw' an error. The call to 'assert' doesn't add any value to
that (and generates less readable error messages, too). Further details are
available at <https://github.com/NixOS/nix/issues/56>.
