I'm pretty much OK with this - sad about the increase in build time but
oh well, I agree the previous situation was awful. The one thing I was
hoping to test was support on other architectures... not that we're in
particularly good shape with that as it is, so I suppose it's not the
end of the world either way.

Consider this my retrospective ack.
