[Boost-build] Modifying build properties within toolset

I'm trying to change the way the darwin toolset works, specifically for 
"universal" (<architecture>combined) builds.

What I'd like to do is have it behave as if I had done 
<architecture>power,x86 (and so generate two sets of everything) and 
then have a separate step where I run "lipo" on each pair of libraries 
or executables to create a universal library or executable.

I was thinking of doing it in the "run" method of a custom linking 
generator class, but I'm not sure if that's early enough in the build 
process.

I thought I had seen it documented somewhere exactly when and how 
virtual targets are created and the calls that are made to generators, 
etc., but I haven't been able to find it or figure it out yet.

Thanks,

Phillip
