src/qml/jsruntime/qv4global_p.h line 94 always triggers,
because x32 is detected as amd64 (Q_PROCESSOR_X86 and
Q_PROCESSOR_X86_64 are defined and QT_POINTER_SIZE is 8)
by qtbase5-dev (src/corelib/global/qprocessordetection.h).

Changing qprocessordetection to set QT_POINTER_SIZE to 4
for x32 won’t help because src/qml/jsruntime/qv4global_p.h
line 91 would then misdetect it as i386. (It would still
be more correct, but I don’t know if that would break
things that work, for now.)

I would prefer doing the right thing here, ie, wether further patching is needed before jumping to disabling JIT.
