From: Harish Sadineni <[email protected]> Conditionally add 'clang-native', 'rust-native' and 'bindgen-cli-native' to 'DEPENDS' when Kernel Rust Support is enabled.
These tools are required for building Rust-enabled kernels and for generating Rust FFI bindings via bindgen during the kernel build. This ensures the additional dependencies are only pulled in when Rust support is explicitly enabled, avoiding unnecessary native dependencies for non-Rust kernel builds.
