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.
Thanks,

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.
