Subject: Re: [PATCH 1/2] kbuild: create built-in.o automatically if parent
 directory wants it

Hi Masahiro.

Thanks for picking this up.

Good observation!

The need-bultin may also be required for the shortcuts
that allows one to use:

	make <dir>/

    example:

	make net/

And maybe selftest, documentation shortcuts too?
Other than that - looks good.
