When calling the `rust_is_available.sh` script, we need to make the
jobserver available to it, as commit ecab4115c44c ("kbuild: mark `rustc`
(and others) invocations as recursive") explains and did for the others.

Otherwise, we get a warning from `rustc`. Thus fix it.

Applied to `rust-fixes` -- thanks everyone!

To be clear, this happens (only) when calling `make` with parallel
jobs, e.g. `-j8`.

Which does not really matter for that target, but nevertheless, some
of us call `make` with jobs enabled most of the time.

Cheers,
