Cross-compiling for arm with a minimal build fails due to syncqt at configure time

I have a minimal build with -no-gui (if it's relevant), where I build my host tools. And then I pass the path to that with -qt-host-path. But the build itself fails at configure time because it compiles and attempts to run the target syncqt during configure time.

Configure log attached.

Configured with:

../src/configure -debug -prefix /opt/qt/arm -qtnamespace qt -force-debug-info -opensource -confirm-license -nomake examples -no-pch -qt-host-path /opt/qt/host/ – --trace --trace-expand --trace-redirect=configure.log
