I'm not sure about an official Boost solution, but the Adobe open
source libraries use Boost to build their stuff (bbv2 only) and in
there we have patches to build i386/pcc/universal, and I would imagine
it would be pretty easy to add ppc64 to the architecture list as well.
Within our projects we have various settings that force other flags
(ie., building release forces a universal binary to be built.) I'm not
sure how elegant a solution it is, but you're welcome to take a look
and see if there's anything in there that will help you out.

On a related note, I hear there is a bona fide architecture setting
built deep into bjam for the 1.34 release, but due to stability
requirements we are sticking with 1.33 for the time being.
