I just do "MakeDist -a" as user and untar the result as root. Script appended.

#!/bin/sh
# MakeDist - build Linux kernel installation tarballs
# written by Olaf Titz, 1999-2000. Public domain.
#
# Call this as MakeDist [-a] [kernel-source-dir]
#
# This will create two tarballs in the kernel source dir:
# boot-x.y.z.v contains /boot and /lib/modules stuff
# inc-x.y.z.v  contains /usr/src/linux-x.y.z/include
# The "v" name component is the build number from .version.
#
# The "-a" argument does a "make dep bzImage modules" cycle
# before building tarballs.
