Rust support in the kernel (`RUST`) defaults to off at the moment, so
if created a new configuration from scratch, it is likely that it
ended up disabled, which in turn makes everything that depends on Rust
disappear, including `RUST_EXAMPLE`.

Please check in `General setup` --> `Rust support` if it is enabled.

HTH,

Cheers,
Miguel
