Just for the sake of people who haven't seen this before.

When I was at MontaVista, and now that I'm at Wind River we use RPM for 
cross compilation.  In both environments, we only ever use a single 
--target=<arch>.  We simply haven't experienced a reason to specify 
multiple architectures on the command line.  (We just run the RPM 
command twice..)

If this fits the expected RPM model, then I'd advocate removing any 
complications for aggregating multiple --target, and just make the 
person run the rpm multiple times.
