britney short-circuits the architecture loop as soon as an
installability problem is detected on one architecture, presumably on
the grounds that we know the package can't migrate so there's no point
checking further.
It's something we've discussed changing every so often and that might be
more feasible now that britney runs are typically in the order of a few
minutes rather than a few hours. It could do with some benchmarking
first though, given that a problem with e.g. eglibc would then involve
checking all of the reverse-dependencies on 13 architectures even though
we know that one of them is uninstallable on i386 (which is currently
the first architecture britney checks).
