Thanks. That's looks indeed like a good example that affects more people 
than just a handful of Qt devs. Will add a note to the report and adjust 
the prio.

The alternative approach for this case is to enable QT_BUILD_WITH_TOOLS 
for the yocto build and rely on binfmt_misc to transparently execute arm 
binaries.
