It looks like the original comparrision was incorrect:
host platform - system on which the binary will run
target platform - system for which compiler generates code
(used with compilers)
build platform - system on which the build is invoked

see: https://nixos.org/nixpkgs/manual/#sec-cross-platform-parameters

This change allows to cross compile busybox on OS X

Motivation for this change
Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.
