Wow that is a lot simpler... if you know it.
When trying to figure this out I googled the original patch that added the savedefconfig and it doesn't mention this Makefile magic; I guess it was added later.
In fact, this has been there almost forever. The rule is in scripts/kconfig/Makefile on line 354.
There are a lot of nice Make targets available. Just try "make help".
