Use the --owner= and --group= options to make sure the entries in the built tar file are owned by root. Without this change, a careless sysadmin using the tar-pkg target can easily end up installing a kernel that is writable by the unprivileged user account used to build the kernel. Test that these options are understood before using them so that non-GNU versions of tar can still be used if the operator is appropriately cautious.
