I don't see a benefit of that... When a build fails, it kills all
other current builds of other architectures, so you need to check that
architecture, that fails first and the diff would not contain the error.

Other that that. The diff would show, different which different
packages are installed, e.g. gcc.i386 instead of gcc.x86_64, which
doesn't interest me either...
(And different requires etc.)

What would be the benefit of such a feature?
