My proposal is to check if the contents are different (use cmp?) and not
pester the sysadmin if there is no change.

I believe this is a simple change and doesn't depend on multiarch, or
anything else.  Simple rule.  If the rpm would install a config file, and
iff the config file exists and is different than the one being installed,
then create .rpmnew and tell human.
