Cross-compilation from Linux to Darwin fails with "infinite recursion encountered"

[thomasjm]

Describe the bug

I can't get any cross-compilation from Linux to aarch64-darwin to work, even for the simplest examples.

For example, I tried adding a Darwin output to this project: input-output-hk/haskell-nix-example@cf52d30.

On this and all other examples I've tried, I get an error like the following. I'm not sure if this is even supposed to work, feel free to close if it's not supported.
