Whithout this path, default platform is automaticaly set (generally
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.
