That setting should not leak into recipes, and should only matter from do_package onwards. Can you look into the rpm recipe please?

 dnf and dnf related packages expecting rpmdb support in libresolv. I
do not know dnf well enough to fix it and moreover it has no direct
use for my usecase either. I also don't see a point of entertaining
dnf for non-rpm backends. Its not intended for that either even if we
were to make dnf not want rpmdb what good will it do to build for
distros who do not use rpm. These changes do not change poky defaults
which use rpm as default. OE-core does not and I dont know of any
opkg user who also has rpmdb needed.
