Due to https://sourceware.org/ml/libc-alpha/2017-04/msg00115.html in glibc 2.26.

TL;DR: the new glibc's unistd does pull in glibc's header for getopt before we include gnulib.

I need to:
1. find a workaround for libvirt in artful to work "as before" pulling in gnulib - maybe pre-including, but that is hard as it could be so many places.
2. get to a reproducer that is good to show the problem
   Why does gnulib work on old and new level in artful/zesty - write a rather simple repro to
   check. With that report to mailing lists.
