[Development] Notice to all packagers: Qt 4 mistakenly detects GCC6 as a different ABI

[Thiago Macieira]

You may start getting this error once you upgrade the compiler:

  Plugin uses incompatible Qt library
  expected build key "x86_64 linux g++-6 full-config", got "x86_64 linux g++-4 
full-config"
"The plugin '/usr/lib64/kde4/plugins/styles/breeze.so' uses incompatible Qt 
library. Expected build key "x86_64 linux g++-6 full-config", got "x86_64 linux 
g++-4 full-config"" 

The configure script needs a simple patch to recognise GCC 6 as the same ABI as 
GCC 4 and 5. Please apply it to your Qt 4 builds if your distro is switching 
to GCC 6.
