qt5base-lts/qmake/option.cpp
Joerg Bornemann 98a3634299 Make qmake and qtpaths report Qt version baked into the binaries 
QMake and qtpaths used qVersion() to report Qt's version number. This is
problematic if those tools are run in an environment where a different
Qt version is loaded (e.g. by setting LD_LIBRARY_PATH).

This reverts commit a783c3d574, which
changed the use of the QT_VERSION define to a qVersion() call in qmake.
Additionally, we use QT_VERSION in qtpaths too for consistency.

Pick-to: 6.5
