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.
This also means that allyesconfig will depend on rust, but since the
rust experiment concluded with "rust is here to stay", i believe that
allyesconfig should be building rust drivers too.
