Time when QMAKE_POST_LINK commands are executed is different between platforms

Building an application using QMAKE_POST_LINK commands, the time when the commands are executed is different on Windows and Linux.

On Windows commands are executed after $$TARGET is copied to $$DESTDIR and Linux commands are executed before $$TARGET is copied to $$DESTDIR.

I made a test application which illustrates this behavior.
On windows build succeed cause $$TARGET is an $$DESTDIR at the time when copy command is executed, but Linux build fails cause $$TARGET is not yet in $$DESTDIR.
