dclock fails to build from source in unstable on 32bit time64
architectures such as armel and armhf. An armhf build ends as follows:

This is due to a toolchain change causing -Wincompatible-pointer-types
to become an error. The reproducible builds infrastructure does not yet
see the failure as it last rebuilt the package in May. I've first
observed this in a cross build, but it actually reproduces natively.
