this change happened in
https://salsa.debian.org/kernel-team/linux/-/commit/929891281c61ce4403ddd869664c949692644a2f
(actually earlier, then reverted and enabled for a subset of
architectures wiith the above commit).
For the Debian build it adds as well the Build-Depends on dwarves (>=
1.16~).
Did I understood your question correctly?
