Original change's description:
> Do not emit colors when building rust
>
> Color codes don't get rendered or escaped in our build logs [0], so we
> end up with stuff like:
>
>  [0m[0m[1m[32m   Compiling[0m proc-macro2 v1.0.63
>  [0m[0m[1m[32m   Compiling[0m unicode-ident v1.0.9
>
> Removing colors should make our logs much readable.
>
