qmake: When the target is empty then it will end up with creating a target called ".exe" on Windows

qmake: When the target is empty then it will end up with creating a target called ".exe" on Windows. I understand that this is expected behaviour, however when qmake -project is used in Qt 4.8 then the default behaviour was to create a pro file that did:

"TARGET = "

which would cause this behaviour to happen in Qt 5.0. Since it is an easy fix to a pro file then could a warning be added to indicate this when qmake is called pointing out that the target is empty?
