* guix/build/cargo-build-system.scm (build, install): Pass the features to cargo. (check): Remove indirection layer for consistency with build and install. * guix/build-system/cargo.scm (cargo-build): New argument; pass it into the builder. * gnu/packages/rust-apps.scm (ripgrep): Use the new argument instead of a custom phase.
