Add cargo check to rust tool chain

[rnpridgeon]

Rust's compiler is notoriously slow which can drastically increases the feedback loop for compilation errors.

This may not be super painful for local builds but it can cause a lot of heart burn when using a remote builder as your clients need to adjust their timeouts based on how long they think a rust build might take. This is a less than awesome trade off which I'm hoping can be mitigated with a simple correctness check.
