Idea: It would be nice if we could do what you just did, then export
/tmp/armdest via NFS, then on arm system mount host:/tmp/armdest /tmp/armdest
and the src and obj trees.  And then somehow run a make installworld \
TOOLSDIR=/tmp/armdest, this would solve your problem with what I believe to be a very \
mininmal change/enhancement to the make system.
