kbuild: allow empty board directories
U-Boot has compelled all boards to have board/${BOARD}/ or board/${VENDOR}/${BOARD}/ directory. Sometimes it does not seem suitable for some boards, for example Sandbox. (Is it a board?) And arcangel4 board has nothing to compile under the board directory. This commit makes the build system more flexible: If '<none>' is given to the 6th column (=Board name) of boards.cfg, Kbuild will not descend into the board directory.
