request #22596: Drop the C toolchain from the Nix shell dev environment
The dev environment provided by nix-shell is built upon `mkShell`, which itself comes with a predefined set of dependencies via the standard build environment [0]. The default stdenv have a complete C toolchain which we do not need for our day to day work. Dropping it reduces the size of the closure with no disadvantages for our context. Before: ``` $ nix path-info --closure-size --human-readable $(nix-build --no-out-link -A inputDerivation shell.nix) /nix/store/zx4kndaxla7zqflpn8q6w96snfw8v2cc-nix-shell 1.2G ``` Now: ``` $ nix path-info --closure-size --human-readable $(nix-build --no-out-link -A inputDerivation shell.nix) /nix/store/m7xsdsknihn9nvqr5prblkwbg3w7hfn7-nix-shell 1021.2M ``` [0] https://nixos.org/manual/nixpkgs/stable/#chap-stdenv Change-Id: Ieb95390569937de4c0543f27d88b6d358be51945
