Cannot bootstrap GHC on aarch64

[tdimiduk]

I have a new mac (m2 cpu) and am trying to get reflex working on it (so I can build an iOS app for my obelisk project). I've got nix installed and (I believe) the caches enabled.

When I run try reflex I get

       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

       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.```

And then when I run with

export NIXPKGS_ALLOW_UNSUPPORTED_SYSTEM=1

I get

I am able to install and run ghc in nix (though 9.2.8 not 8.10)
