Currently, we only require a gcc 4.4 version, which now is pretty old (released in April 2009). This requirement is not even tested nowadays, with our oldest autobuilder having a 4.7 version only. And even then, 4.7 is still old enough that it prevents us from upgrading some packages. For example cmake 3.10+ requires C++11 constructs that were only added in gcc 4.8 (when C++11 support was finally completed in gcc). So, update our requirements for gcc to at least 4.8.
