In this case you don't actually need a cross-compiler, since Nix on x86_64 can
do x86 builds just fine (through the personality() syscall).  So you can just do
something like:

  $ nix-build '<nixpkgs/nixos/release.nix>' -A iso_minimal.i686-linux

or more generally, to build a NixOS configuration:

  $ nix-build '<nixpkgs/nixos>' -A config.system.build.toplevel \
      --argstr system i686-linux
