Makefile: sparc/sis builds again

+ sparc did not really have a unique in_cksum.c and Makefile
    needed to be adjusted to reflect this
  + some destination directories for copied files did not exist.
    make the destination directory before copying.
    This is really not a great thing to do as it messes with the source
    tree but it works for now. It would be better to make a special
    place to put generated source and integrate that into the build system.
