Thanks for the explanation. That just leaves one question: why are we
bothering to create and populate ${INSTALLTMP}? Under normal
circumstances, where ${WORLDTMP} exists, it doesn't seem to be used.
In fact, it's missing the 'strip' binary, but it doesn't make a
difference until I come along and try to run without ${WORLDTMP}...
As for the rest, if the process is unsupported, then I guess I will
stop doing it :) ... but I'd just like to state for the record that it
seems to work perfectly fine here, after these workarounds. I think
it's also possible to have a "correct" solution, by using the freshly
built world instead of ${WORLDTMP} when ${MACHINE_ARCH} says so. If
there is any interest at all, I can get that working and submit a
patch.
