We are migrating packages that meet below requirements:
1. using `callPackage`
2. called path is a directory
3. overriding set is empty (`{ }`)
4. not containing path expressions other than relative path (to
makenixpkgs-vet happy)
5. not referenced by nix files outside of the directory, other
than`pkgs/top-level/all-packages.nix`
6. not referencing nix files outside of the directory
7. not referencing `default.nix` (since it's changed to `package.nix`)
8. `outPath` doesn't change after migration
The tool is here: https://github.com/Aleksanaa/by-name-migrate.
Without the change the instantiation in `linux` fails as:
$ nix-instantiate -A wine

a) To temporarily allow packages that are unsupported for this system, you can use an environment variable
for a single invocation of the nix tools.
$ export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1
Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
then pass `--impure` in order to allow use of environment variables.
b) For `nixos-rebuild` you can set
{ nixpkgs.config.allowUnsupportedSystem = true; }
in configuration.nix to override this.
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowUnsupportedSystem = true; }
to ~/.config/nixpkgs/config.nix.
Wine supports a form of futexes on Darwin when built with the 14.4 SDK
and running on 14.4 or later. It will fall back automatically to other
primitives when running on older systems.
