I should ask upstream about this. However, I get these warnings also
when I successfully build with `debian/rules build`. I attach the
successful log at the bottom. The main difference I see compared to
the failing log (running pkg-buildpackage), is that the successful
build does:

ln -sf libcuba.so.4.2 libcuba.so.4
ln -sf libcuba.so.4 libcuba.so

...
The only serious difference between dpkg-buildpackage and debian/rules is that dpkg-buildpackage will automatically apply patches while debian/rules build will not (you have to do it manually, e.g. dh_quilt_patch).
Do you have something in debian/patches that dpkg-buildpackage is applying to the source, that might be fouling up the build conditions?
I do have patches to create the shared objects and add hardening flags. Since I get both also with `debian/rules build` I was assuming the patch is applied.
However, playing back with the original source without patches I noticed that the undefined reference error originated when compiling in parallel. Setting --no-parallel in debian/rules I build successfully also with debuild. Thanks for the tips!
(Indeed, looking at the logs the succesful `debian/rules build` was running without parallelization, and the failing dpkg-buildpackage was running in parallel.)
I still get the ‘memcpy’ pointer overflow warning when using hardening flags, I'll notify upstream.
If not, do you have a chroot (e.g. pbuilder, sbuild, or debian project machine) you could use to build with?  That eliminates any random deviations in your system configuration. 
With --no-parallel I build successfully also with pdebuild.
I am now going through the remaining lintian warnings. I have a doubt about the following:

However, I adapted this paragraph from section `5.2.1. Example files paragraphs' of the link mentioned above. To me it looks fine as it is, am I missing something? I report debian/copyright below. 

Thanks,
Francesco
