Yeah, it is the "old way" for many architectures, but nowadays
`LLVM=1` is the recommended way for most (in the last couple years a
few architectures got promoted from `CC=clang` to `LLVM=1`).

Given that most arches are `LLVM=1` nowadays, including those that we
currently support Rust for, and that perhaps by the time e.g. s390
supports Rust it is also a `LLVM=1` architecture, we should probably
just remove `CC=clang` at this point and perhaps add an extra link to
Documentation/kbuild/llvm.rst again just in case (the link is also
elsewhere in that document, but I guess it does not hurt).

I will send a patch.

It does -- thanks a lot!
