To enable Rust integration in the Linux kernel build, this patch:

- Adds `rust-native`, `clang-native` and `bindgen-cli-native` to `do_kernel_configme[depends]`
  to ensure required tools are available for Rust support.
- Invokes `make rustavailable` inside `do_kernel_configme()` to prepare
  the kernel for building Rust-based modules or core components.

And here's the answer to my previous question.

To me, this patch should be squashed with 05/16.

OK Bruce, I’ll combine this patch with 05/16 and send it as v2.
