[Boost-build] Building universal libraries and binaries on OS X

I'm trying to add support for building universal libraries, and I'm not 
sure where to start on the next step.  I've got it so that we can 
compile for either OS X platform (or both).  The next step is to run 
"lipo" on the resulting libraries and/or executable to make a "fat" binary.

I'd prefer that it be automatic on when you request the universal build 
instead of having to have a "lipo" rule that has to be added to each 
jamfile.  So, I suspect I need to override the linking generator and 
have it request the two platform builds and set up the target to lipo 
them together.  I'm pretty sure I can get it to lipo them together once 
I get the builds done, but I'm not sure how to trigger the other two 
builds.  Can someone point me in the right direction?

Thanks,

Phillip
