Place the .config file in the output directory. This makes it easier to have multiple output directories with different configurations as "make OUT=out-${config}/" will automatically switch to the correct configuration. It also allows to do parallel builds of different configurations.
To simplify transition copy over the .config file in case there is one at the old location but not at the new location.
