Now Jessie has entered LTS the powerpc architecture has been dropped
so we can no longer build the image from scratch. However we can use
the snapshot archive to build the last working version.
This now only lives on an example of setting up a user-cross image as
at least on x86-64 we can use the Buster packaged cross compiler for
building test images.

We can't use cross compilers in the current Debian stable and Debian
sid is sketchy as hell. So for powerpc fall back to dog-fooding our
own linux-user to do the build.
As we can only build the base image with a suitably configured
source tree we fall back to checking for its existence when we can't
build it from scratch. However this does mean you don't have to keep
a static powerpc-linux-user in your active configuration just to
update the cross build image.
