"make localmodconfig" Create a config based on current config and
                      loaded modules (lsmod). Disables any module
                      option that is not needed for the loaded modules.

                      To create a localmodconfig for another machine,
                      store the lsmod of that machine into a file
                      and pass it in as a LSMOD parameter.

              target$ lsmod > /tmp/mylsmod
              target$ scp /tmp/mylsmod host:/tmp

              host$ make LSMOD=/tmp/mylsmod localmodconfig
