gettext, libiconv: Make setup hook work for cross

[Ericson2314]

Motivation for this change

Fixing my concern from https://github.com/NixOS/nixpkgs/pull/37012/files#r174660554. The method and comment is taken from the cc-wrapper and binutils-wrappers setup hooks. (Should we abstract it instead?)

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option build-use-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 nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.

It probably needs to be done for libiconv too.
