It doesn't work because make libafs_tree only includes the files required
for the architecture one runs it on.  The OpenAFS Debian packages switched
from a full copy of the source tree to using libafs_tree in that time
frame.  I haven't had a chance to try to fix it yet.  If someone else beat
me to it, I definitely wouldn't complain.
