I'd suggest trying to get PCPA's attention on this. I remember a few years
back we ran into some problems building QT4 on arm.

Hello guys.
Month (or a little bit more) ago i wrote script that allows you build arm
packages on x86 machine.
Well, it's working fine with a lot of packages except qt4 stuff.
For example you can build simple qt4 package like akonadi
sh build.sh akonadi
And after 5 minutes you got an error like
/usr/lib/qt4/bin/qdbuscpp2xml
/home/user/rpmbuild/BUILD/akonadi-1.9.2/server/src/debuginterface.h -o
/home/user/rpmbuild/BUILD/akonadi-1.9.2/build/server/org.freedesktop.Akonadi.DebugInterface.xml

Need help to solve this issue.
I spent to this a lot of time, i recomliled qemu with few patches that
trick /proc/cpuinfo
i switch versions of qemu between 0.xx and 1.5.1
Few hours ago i pushed to repo qemu-wrapper that adds -cpu cortex-a8 to
qemu binary.
I did a lot of strange things, now i need help.
You can simply reproduce it
1.clone crossbuild
2.tune qemubinfmt/build.sh for your specs
3.sh build.sh akonadi
