parallel multi-machine builds have been discussed but not thought of worth doing. you could however share
lot of common packages among machines sequentially.

MACHINE=foo bitbake x
MACHINE=bar bitbake y

the second invocation would be able to share many artifacts from first builds e.g. native packages
and nativesdk packages etc. so its generally faster than first build.
