Follow-up to #269551 Avoid creating a new instance of nixpkgs to access two variables. `pkgs.pkgsi686Linux` was being accessed whenever the feature is being used or not. A second instance of nixpkgs is being created in `nixos/modules/config/stub-ld.nix` and can be disabled by setting `environment.ldso32 = null` or `environment.stub-ld.enable = false`. Both combined fixes this error: error: attribute 'i686-linux' missing
