An update on this: Ubuntu now provides the versioned `rustc-*`
packages in older LTSs (the ones with standard support), which is
great!

I can confirm I can build the latest kernel in 20.04 LTS (using a
newer LLVM), 22.04 LTS, 24.04 LTS and 24.10.

The `bindgen-*` versioned packages are not backported (yet?) to the
older LTSs, so users need to build `bindgen` manually in 20.04 LTS and
22.04 LTS. For 24.04 LTS and 24.10, it works with the package. I will
add a sentence about that and send the non-RFC patch.
