I certainly hate the idea of adding another 32-bit port to Debian.
I think that it's OK for traditional distros to say 'just upgrade to
64bit' while you solve the problem for 32-bit embedded systems where
there's probably little demand for supporting multiple ABIs at once.

dpkg multiarch covers this just fine, while I believe RPM is limited to
biarch.

Didn't we need to do this already to support x32? Have compat ioctls
involving time been botched?
