I cannot duplicate the problem.  It must have to do with the way your particular system is setup.   What is interesting is that the -lz is not actually called on my system, where I most certainly don't have the libz devel package installed.  I am guessing there is a configure failure of some sort?

Do you think on the fedora28 system you could send me the "rpm -q -a" output?
