> set to "eglfs" as defined in
> qt5base/mkspecs/devices/common/linux_device_pre.conf:1). This choice
> is not always what the user would like. Thus, user have to manually
> appends "-platform <BACKEND>" to command line when running any qt5
> application.
> 
> This patch allows user to choose default platform explicitly.
