qtprofilesetup: Fix check for static Qt.

On Windows, the DLLs are in the BINS dir, not in LIBS.
The reason this seemed to work so far is that the Qt packagers randomly
put the DLLS into the LIBS directory for certain releases. For instance:
   Qt 5.4.2/MSVC: no
   Qt 5.4.2/MinGW: yes
   Qt 4.8.7/MinGW: yes
   Qt 4.8.6/MinGW: no
Fun!
