When `stdout` is not visible, e. g. when piping the output of `cargo llvm-cov` to a file, it seems like `cargo llvm-cov` hangs without doing anything when the `llvm-tools-preview` rustup component is not installed. `stderr` is less likely to be redirected, so asking on there is less likely to not be visible.
