Fine, this should be detectable.

What would the value be for MSVC where there's a separate compiler 
binary per target architecture?

Could we explicitely pass the architecture argument to gcc/clang in 
every case and not rely on the default?

If there's postprocessing involved for combining builds, then this 
should be a property of some kind of meta project that builds a 
subproject with different build configurations and then does something 
with the build result(s). I agree with Ossi that this looks a lot like 
like a list of profiles.
