I see. There is nothing in kbuild that will help you to achieve this. If you build the kernel and parse all .*.cmd files then you can build a complete list of files used and create your symlinked tree. But then you need a fully build kernel to do so.
I see no easy way to get the info without building the kernel and if we do this only as a preprocessing step then we will most likely not integrate it in kbuild since the user base will be small. But if you hack up something lets take a look at it.
