you can generally do
$ make foo-clean && make foo
Note that foo-dirclean deletes the whole sourcestree of foo, so make
sure to save any change you did to a corresponding
foo-descriptive-description.patch.

Also note that in order to configure busybox with the correct settings
you are supposed to run 'make busybox-menuconfig'. See docs/README

the kernel is the one exception. It's clean target is called
linux26clean (i.e. no dash!) for reasons explained near that target.
