I am not totally convinced by this solution. If we adopt it, somebody who
installs e.g. octave on an old system-z machine will be hit by a failure in the
dpkg installation process, which needs manual intervention. This is likely to
generate problems in automated installers (and also confuse and annoy system
admins).

I leave that to the s390 porters to answer.
