Maybe you need to be thinking about a script that is "outside" the build
system: run the configure/make/make install process 4 times, then
combine the results.  You could use the fact that some file is not the
same in all 4 install trees as the trigger driving a combination
process.  (Shades of multilib RPMs ...)
