I like this idea a lot too. It will speed up development. :)

If the -main- development is done this way, then a final compile for  
the release is done on actual hardware with the actual toolchain, it  
would also meet the specs of the Fedora Project.  This is less  
frustrating to developers, and it should only require a 1 recompile  
since the build issues should be fixed.

While adding the armv7l flags, can we also double check for the  
existence of the armv5tel flags and add them if necessary especially  
in the f15 and f16 packages? :)
