Subject: [PATCH v5 0/4] EDITME: RISC-V: re-enable gcc + rust builds

Previous v4 patch:
https://lore.kernel.org/rust-for-linux/20251124-gcc-rust-v4-v4-0-4e06e07421ae@gmail.com/T/#t

Compared to v4, this v5:
- Placed `include Makefile.rust` under `ifdef need-compiler` branch. From my local testing, this did not cause any issues.
- The Kconfig function now only tests backend flags and has been renamed to `bindgen-option`, without depending on environment variable. Added a comment explaining the meaning of "backend".
- Improved the wording of commit messages and provided further details.

      rust: export BINDGEN_TARGET from a separate Makefile
      rust: generate a fatal error if BINDGEN_TARGET is undefined
      rust: add a Kconfig function to test for support of bindgen options
      RISC-V: handle extension configs for bindgen, re-enable gcc + rust builds
