[QGIS-Developer] issue compiling current master

[Daniele Viganò]

I was able to identify why it's failing when building packages, but not on
QGIS Travis and/or when making a simple compilation from git: hardening!

Packages on Fedora are built with gcc hardening set (this is usually
required by packaging policies). Unfortunately Travis is not testing this
environment. I added a full description of the problem here:
https://github.com/qgis/QGIS/pull/7319#issuecomment-401261273

This problem may affect other distributions, like SuSE. Not sure about
Ubuntu/Debian, but I would expect hardening enabled by default also on them
nowadays.

Thank you very much.
