- Alternative build method: 'make kernel-links'

          based on 'makelinks' script in dvb-kernel cvs.
        - Symlink cvs code into kernel source in order to build cvs code
          inside kernel build.
        - Currently requires merged-trees, because of some missing files
          in v4l-kernel cvs, present in dvb-kernel cvs, such as Makefile
        - 'make kernel-links' will automatically call 'make merge-trees'
        - Currently requires a patch to linux/include/linux/videodev.h,
          which adds #include "compat.h"  Patch is applied during
          'make kernel-links' and is removed during 'make clean'
        - videodev.h patch and merge-trees dependency can be removed in
          the future.
