But it's not the case as far as I can see.

in busybox.mk:

busybox-menuconfig busybox-xconfig busybox-gconfig: busybox-patch

in pkg-generic.mk

$(1)-patch:             $(1)-extract $$($(2)_TARGET_PATCH)

$(1)-extract:           $(1)-source \
                        $$($(2)_TARGET_EXTRACT)

$(1)-source:            $$($(2)_TARGET_SOURCE)

and that's it. Nowhere it pulls 'dependencies' as far as I can see.
