A single build machine can cross-build for multiple environments so you
really only need one machine.

In general, backward compatibility is supported, so a world built on a
RELENG_7 box should be able to be installed by a RELENG_7_1 target
(though not by a RELENG_6_4 target). And you can run into he same
problem with different i386 variants - if your build machine is built
with (eg) P4 options than a generic world built by that box cannot be
installed by (eg) a P2 due to instruction differences.
Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
