Making nixos keep a ref to its stdenv

Browse source 
This will help a lot on ARM, where nix-collect-garbage erases gcc; then, any
change to a small system config file requires rebuilding gcc again.

I don't know why it does not happen on x86. Maybe it just pulls the gcc from
hydra, if garbage is collected.
