It cannot be enabled yet together with Rust, so no worries, but I need
to remember to update this patch:

    https://lore.kernel.org/rust-for-linux/20241119185747.862544-1-ojeda@kernel.org/

So I will reply there with a backlink to this.

I guess since we need to rebuild even `core`, I may need to add
something like the `fixdep` workaround we have to rebuild on
`RUSTC_VERSION_TEXT` changes.

Thanks!

Cheers,
Miguel
