Nowadays all architectures except s390 recommend using `LLVM=1` instead of

docs") the Kbuild LLVM documentation makes `LLVM=1` the way to go:
We want to encourage the use of ``LLVM=1`` rather than just
``CC=clang``. Make that suggestion "above the fold" and "front and
center" in our docs.
In particular, that commit removes the examples with `CC=clang`.
Thus do the same in the Rust Quick Start guide, i.e. remove the `CC=clang`
mentions, especially since the architectures that have had their Rust
support upstreamed (or soon to be upstreamed) are all `LLVM=1` ones
anyway. And perhaps by the time Rust is supported for s390 (or new
architectures), it may have moved to `LLVM=1` anyway. Otherwise,
this can be added back if needed (or perhaps an extra link to
Documentation/kbuild/llvm.rst).
This should also help avoiding potential confusion around `CC=clang` [1].
