[Development] MinGW configuration change on 5.11 branch?

[Thiago Macieira]

Twice an integration of mine resulted in 

 ..\..\..\..\shared/emulationdetector.h:62:13: warning: 'bool 
EmulationDetector::isRunningArmOnX86()' defined but not used [-Wunused-
function]
  static bool isRunningArmOnX86()
              ^

Has something changed? if so, can whoever made the change roll it back or fix 
this issue, please?
