Is it completely necessary to cross-compile the tools?  I simply built them on
the target platform itself, which in my case is the Arndale, but while I have
not had any problems using this method, Ian may know of some reason why this
should not be done.

The process for Ubuntu is first log onto the target platform and configure the
necessary packages:

sudo apt-get update
sudo apt-get install build-essential
sudo apt-get build-dep xen
sudo apt-get install libgtk2.0-dev libfdt-dev libaio-dev
sudo apt-get remove dh-ocaml libfindlib-ocaml ocaml-base-nox ocaml-findlib
ocaml-interp ocaml-nox

Finally build and install the tools (Make absolutely sure that you build the
tools from the same git hash that you built your Xen image, or you will have
interesting problems.):

./configure PYTHON_PREFIX_ARG=--install-layout=deb --libdir=/usr/lib
make dist-tools
sudo make -C tools install
sudo update-rc.d xencommons defaults 19 81
sudo update-rc.d xendomains defaults 21 79
