Yeah, Rust is adding few strings with paths (at least ~4 KiB from a
quick test in my case); while a non-Rust kernel, in-tree build without
`DEBUG_KERNEL` does not seem to contain any absolute paths (although
please note that kernels typically contain your username/host anyway
unless you tweak `KBUILD_BUILD_*` etc.).

So while I don't think it is that critical at the moment, any bloat
that can be reduced (e.g. those paths could be relative) is always a
good idea. It is also good for improving reproducibility of builds
etc.

I will create a quick issue about this.

Thanks!

Cheers,
Miguel
