Default configurations, as per "make savedefconfig", only record differences to the default.
There will be no "CONFIG_NET=y" in a defconfig if "select NET" configures it automatically.
This is per design to reduce the size of the configuration file. On the downside,
it means that a "simple" change such as "select NET" -> "depends NET" has far reaching
consequences.
