Qt fails to compile to windows QNX build

https://code.qt.io/cgit/qt/qtbase.git/commit/src/corelib/global/qsystemdetection.h?h=5.14&id=9b8493314dd77f3e96b353187816bb7ef4dedbb5 added the line

# if QT_VERSION >= QT_VERSION_CHECK(6, 0, 0)

to /src/corelib/global/qsystemdetection.h.  QT_VERSION and QT_VERSION_CHECK are defined in qglobal.h, which is included via

#ifndef QGLOBAL_H
# include <QtCore/qglobal.h>
#endif

at the top of that file.

The problem is that config.tests/arch/arch.cpp starts with:

#define QGLOBAL_H
 #include "../../src/corelib/global/qsystemdetection.h"

Thus qglobal.h is not included, the two macros are not defined, and the arch config test fails.

It looks like CI didn't catch this, as QNX is only built from a Linux host.
