Linker response files for the MinGW and Unix makefile generators are
controlled by the variable QMAKE_LINK_OBJECT_MAX. This variable holds a
number. If the number of object files passed to the linker exceeds this
number, a linker response file containing object file paths is created.
This heuristic is extremely imprecise. It doesn't take into account the
length of object file names nor the length of $$OBJECTS_DIR.
Also, when using a static Qt, a big part of the linker command line are
libraries. A relatively small example can fail to link with "The
command line is too long" on Windows, even with the object files being
in a response file.
The MinGW makefile generator already reads the variable
QMAKE_RESPONSEFILE_THRESHOLD for compiler response files. Re-use this
variable for the linker response file of the Unix and MinGW makefile
generators.
If QMAKE_RESPONSEFILE_THRESHOLD is set, use it to determine whether to
create a response file. QMAKE_LINK_OBJECT_MAX is then ignored. The
response file contains objects and libraries.
If QMAKE_RESPONSEFILE_THRESHOLD is not set, use QMAKE_LINK_OBJECT_MAX to
determine whether to create a response file. The response file contains
only object files.
QMAKE_LINK_OBJECT_SCRIPT is used in both cases to specify a common base
name of all linker response files.

Like Q_NAMESPACE_EXPORT for Q_NAMESPACE, this variant of Q_GADGET
allows passing an export macro. This is useful to avoid exporting the

Before anyone asks: No, we don't need Q_OBJECT_EXPORT, because QObject
subclasses, being polymorphic, always need to have a class-level
export macro (to export their vtable), but while that technique also
works for value classes (the Q_GADGET audience), it is not desirable
for them, because it makes inline functions exported in Windows debug

Extra compilers with "CONFIG += combine" were broken for qmake's vcxproj

Usually, extra compilers are handled by attaching the Custom Build Tool
to the input file. This is not possible for combine extra compilers,
because they map multiple inputs to one output. We cannot attach the
Custom Build Tool to the output either, because this would result in
circular dependency errors (output trying to create output itself).
To fix this, we create a custom build tool fake file (.cbt) for the
output and attach the Custom Build Tool there. This is the same trick
we do for regular extra compilers that have C++ sources as
input (e.g. the one that generates moc_predefs.h).

In a cross built Qt, for example Qt for Android, calling "qmake -spec

"Could not find qmake spec '-qtconf'."
This happened, because:
- the qmake in Qt for Android is a wrapper script that calls
"qmake -qtconf qt_target.conf -spec android-clang"
- the first stage of command line argument handling in qmake garbled the
call to "qmake -spec -qtconf qt_target.conf android-clang"
We do not modify the order of arguments anymore.
Instead, we skip the "-qtconf <file>" arguments in the first argument
handling stage that is supposed to determine qmake's modus

In addition, we need to fix the assignment of
QLibraryInfoPrivate::qtconfManualPath which was only done if
QMakeGlobals::addCommandLineArguments returned ArgumentsOk. However,
this function returns ArgumentUnknown, if it encounters an argument it
