I simply tried to re-use the KBUILD_* env vars whenever possible. This
did made sense, since:

$ dmesg|grep debian
                                                                  ~
[    0.000000] Linux version 4.14.0-0.bpo.3-amd64
(debian-kernel@...ts.debian.org) (gcc version 6.3.0 20170516 (Debian
6.3.0-18)) #1 SMP Debian 4.14.13-1~bpo9+1 (2018-01-14)

and

$ apt-cache show linux-image-amd64| grep Main
                                                                  ~
Maintainer: Debian Kernel Team <debian-kernel@...ts.debian.org>

I do not believe this should take precedence over DEBEMAIL.
