-Finally, as an ad-hoc escape hatch, a computed target (string or JSON file

-This is useful to avoid rebuilding Rust tools, since they are actually target
-agnostic and don't need to be rebuilt. But in the future, we should always
-build the Rust tools and standard library crates separately so there is no
-reason not to take the `stdenv.hostPlatform.rustc`-modifying approach, and the
-ad-hoc escape hatch to `buildRustPackage` can be removed.

 Note that currently custom targets aren't compiled with `std`, so `cargo test`
 will fail. This can be ignored by adding `doCheck = false;` to your derivation.
