qt-everywhere-4.7.4 compile issue

Hello,

I try to set up qt-everywhere 4.7.4 for a ARM architecture with configure:
./configure -embedded arm \
-xplatform qws/linux-arm-gnueabi-g++ \
-v \
-arch arm \
-continue \
-force-pkg-config \
-I /home/oschma/BSP/BSP-Phytec-phyCARD-L-PD12.0.1/platform-phyCARD-L/sysroot-host/include \
-little-endian \
-L /home/oschma/BSP/BSP-Phytec-phyCARD-L-PD12.0.1/platform-phyCARD-L/sysroot-host/lib \
-dbus

N.B. after the configure step I have to correct mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf to enter the correct tools (cpp, g++, ...).
./configure concludes successfully. But at the make step I get an error:

What confuses me is why qatomic_i386.h is used as it should be qatomic_arm.h.

Thanks in advance for your help
