This reduces the build closure substantially since it no longer pulls in the entire C build environment.

For example, using build-project.nix:

With stdenv:

$ nix path-info --closure-size --human-readable $(nix-build --no-out-link -A inputDerivation build-project.nix)
…
/nix/store/v96sbzyinh0zfkk0c13i6dx3hkrlvds1-build-project-output     322.5M

With stdenvNoCC:

$ nix path-info --closure-size --human-readable $(nix-build --no-out-link -A inputDerivation build-project.nix)
…
