Hi Mike,

looking at the code, it seems to me that the tarball target
is not designed to handle the case where the tarball already
exists locally. As a work-around, could unpack the kernel manually.
Note that this won't work if you run make world, as it runs
make kclean, which cleans the kernel directory before building:

# cd xen-3.3.1
# make clean kdelete
# tar -zxf ../../xen-3.3.0/linux-2.6.18-xen-3.3.0.tar.gz
# mv linux-2.6.18-xen-3.3.0 linux-2.6.18
# touch linux-2.6.18/.valid-src
# make XEN_LINUX_SOURCE=tarball dist

Or you could build the kernel(s) separately,
possibly outside of the xen-3.3.1 tree.
