Qt 4.7+ didn't correctly works at ARM platform

Qt simple "hello world" application didn't correctly work on MOXA UC-8410.
We get arm-linux cross-compiler from moxa site and build Qt library from source.
Then we copy libQtCore.so from our computer to MOXA device and start our application, which should output just "Hello, world!", but instead of it we got:

QString::arg: Argument missing: "/proc/%1/exe" ,
4303 Qtig:r:Agmn isn:"po/1ee
33 Qtig:r:Agmn isn:"po/1ee 33

Qt version 4.7
When we use Qt 4.5.1-4.6.3 all works fine.

Configuration we use to compile Qt sources is:

For 4.7.0, 4.7.1, 4.7.2:
./configure -prefix /opt/qt-arm -embedded arm -xplatform qws/linux-xscale-g++ -no-javascript-jit -no-script -no-multimedia -no-audio-backend -no-svg -no-webkit -qt-zlib -no-gif -no-libtiff -no-libpng -no-libmng -no-libjpeg -no-gui -no-nis -no-cups -no-gtkstyle -no-opengl -no-openvg -no-sm -no-xshape -no-xvideo -no-xsync -no-xinerama -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-mitshm -no-fontconfig -no-xinput -no-xkb -no-glib

For 4.6.3:
./configure -prefix /opt/qt-arm2 -embedded arm -xplatform qws/linux-xscale-g++ -no-javascript-jit -no-script -no-multimedia -no-audio-backend -no-svg -no-webkit -qt-zlib -no-gif -no-libtiff -no-libpng -no-libmng -no-libjpeg -no-nis -no-cups -no-gtkstyle -no-opengl -no-openvg -no-sm -no-xshape -no-phonon -no-xsync -no-xinerama -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-mitshm -no-fontconfig -no-xinput -no-xkb -no-glib

Test program:

======= main.cpp file ============
#include <QtCore>

int main (int argc,char **argv)
{
QCoreApplication a(argc,argv);

qDebug() << "Hello world!";

return a.exec();
}
======= end of main.cpp file ============
