So really, one needs to run `make savedefconfig`, copy defconfig to
configs/foo_defconfig and then see if there's some changes / settings
there that are unexpected.  Because if you put a change in there, and
then run `make foo_defconfig` and don't see what you want in the new
.config file, there's a missing dependency or similar.  Thanks!
