There may be a simpler explanation to this, but here's what I did and why.
I assumed that the kernel build within Xen is currently broken for
whatever reason so I built the dom0 kernel separately.

(If anyone can shed some light on why, I'd like to know as well)

To get the xen build to stop building the kernel (as per the README) you can do:
export KERNELS=""
Then it builds xen/xen-tools and no kernel.
