Don’t include Python in libpsl’s build inputs when cross compiling to Darwin. Python does not support cross-compilation to Darwin (see python/cpython#90905), which prevents cross-compiling anything that depends on libpsl (such as curl).

Things done

  • Built on platform(s)
    • x86_64-linux
    • aarch64-linux
    • x86_64-darwin
    • aarch64-darwin
  • For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
    • sandbox = relaxed
    • sandbox = true
  • Tested, as applicable:
  • Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
  • Tested basic functionality of all binary files (usually in ./result/bin/)
  • 24.11 Release Notes (or backporting 23.11 and 24.05 Release notes)
    • (Package updates) Added a release notes entry if the change is major or breaking
    • (Module updates) Added a release notes entry if the change is significant
    • (Module addition) Added a release notes entry if adding a new NixOS module
  • Fits CONTRIBUTING.md.

This should be &&, right? Otherwise static non‐Darwin starts including Python 3.

It might be nice to set broken on Darwin cross Python and base this on python3.meta.broken instead, since I think the other conditional here is because static Python also broke recently…

I hope we can fix this and if not then the conditional should be in python3, but LGTM to unblock this for now.
