[PATCH RFC] Fail the build on RUST=y and RUST_IS_AVAILABLE=n

[Sasha Finkelstein]

The current approach of silently disabling all rust drivers if the
toolchain is missing results in users that try to compile their own
kernels getting a "successful" build and then being confused about where
did their drivers go. In comparison, missing openssl results in a build
failure, not a disappearance of everything that depends on it.
