AFAIK the Barrelfish arm tree for which those instructions were written for
has not been released to the public yet. The one in the current public repo
is vastly outdated and doesn't reflect the current status of the ARM port
Maybe you could ask someone if you can clone the internal Barrelfish for
ARM tree, but I also heard that there will be a public release soon.
