GCC-6 will fail to build with "-isystem /usr/include" (see

According to it is the responsibility of maintainers using qmake in their packages to properly filter '/usr/include' from INCLUDEPATH:

"the problem are the broken qmake-based build systems of 3rd party applications, which somehow end up adding /usr/include to INCLUDEPATH. report bugs against these applications."
