'KERNEL_REGION_BASE' undeclared when building ucLinux with nios2-linux-20090928.tar

I selected NIOS2 without MMU and built the kernel. Then I got the following error.

I use Cent OS 5.3 in one IBM T42 Notebook.

chmod +x tools/romfs-inst.sh tools/modules-alias.sh tools/build-udev-perms.sh

. linux-2.6.x/.config; if [ "$CONFIG_INITRAMFS_SOURCE" != "" ]; then

mkdir -p `dirname $CONFIG_INITRAMFS_SOURCE`;

touch $CONFIG_INITRAMFS_SOURCE || exit 1;
