Adding LSB_DISTRO_ADJUST directly to lsb.py would be fine I think.
Personally I use LSB_DISTRO_ADJUST to map Linux Mint to Ubuntu. Linux
Mint is binary compatible with Ubuntu (created from Ubuntu package
feeds). The LSB_DISTRO_ADJUST mapping allows native sstate from a
build server running Ubuntu to be reused on a developer laptop running
Linux Mint.

  https://github.com/lgirdk/meta-mng/blob/ofw/conf/distro/include/mng-sstate.inc

If the make 4.2.1 sanity check were to include LSB_DISTRO_ADJUST then
(for me at least) it would suppress unnecessary warnings when running
on Linux Mint (ie with the Ubuntu version of make). But in general, if
we give users a method to adjust how their host distro is identified
then we should enable it consistently unless there's a clear reason
not to.
