- API change: remove the `target` argument of `buildRustPackage`, the
target should always be in sync with the C/C++ compiler that is used.

with the installation logic.
We expose it on the top level, but I don't think it makes sense to pull
it from a specific version of the rust tools when it is in fact version
agnostic.
