Whne SYSROOT is defined, clippy-driver will insert a --sysroot argument when calling rustc. However, when a sysroot argument is already defined, e.g. through RUSTFLAGS=--sysroot=... the `cargo clippy` call would error. This tests that the sysroot argument is only passed once and that SYSROOT is ignored in this case.

//! `env INTEGRATION=rust-lang/log cargo test --test integration --features=integration`

//! You can use a different `INTEGRATION` value to test different repositories.
