Qt source build fails (4.8.) on Pixman

? Offline

building qt 4.8.6 on ubuntu 12.04.4 lts with configure:
./configure -platform linux-g++ -arch arm -xplatform qws/linux-arm-g++ -prefix /usr/local/arm -platform linux-g++ -little-endian -armfpa -no-sm -qt-mouse-tslib -fast -no-qt3support -opensource -confirm-license

I'm using:
QMAKE_CXXFLAGS_DEBUG += -march=armv7 -mtune=cortex-a9

tools work, but compile fails:

It looks like the code is not armv7 compatible?
Any help/pointers would be appreciated.

Thank you,
