zsh: command not found: gcc

$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git checkout kirkstone
$ nix develop --impure --no-write-lock-file github:nix-community/nix-environments#yocto
$ gcc --version
gcc --version

Tests done

gcc version used to build Yocto kirkstone is too recent.

I tried the following flake.nix without success:

{
  inputs.nix-environments.url = "github:nix-community/nix-environments";

  outputs = { self, nixpkgs, nix-environments }:
    let system = "x86_64-linux";
    in {
      devShell.${system} = let pkgs = import nixpkgs { inherit system; };
      in nix-environments.devShells.${system}.yocto.overrideAttrs (old: {
        extraPkgs = [ pkgs.gcc11 ];
        stdenv = pkgs.gcc11Stdenv;
      });
    };
}

What is the best way to force gcc11 with nix-environments#yocto?
