compilers/rust: implement has_argument checks

We're about to convert the `b_sanitize` option into a free-form array
whose value gets verified via a compiler check. This conversion will
also impact the Rust toolchain, which does not yet know to check for
multiple arguments at once.

Implement both `has_multi_arguments()` and `has_multi_link_arguments()`
to prepare the code accordingly.
