If they are created once and stored in an archive then you also have
to put sources there. For an example what that means lets show some
numbers. The ia32-libs package has a 20MB deb but ~250MB sources.

The shear size of sources needed for all the libraries and apps one
might need in 32bit is too big to make this practicaly.

We are working on better way, most importantly multiarch, so this is
just an intermittend hack.
