Debian's armel port can't use yield. This regression was introduced in https://github.com/qt/qtbase/commit/877c158c5976bebffd0ff02c39b6b66a842c6344 by mmutz
In order to workaround it we added another precompiler directive to avoid
asm volatile("yield");
if the compiler is not Q_CC_GNU and __ARM_ARCH is equal or more to 7. This will work for us, but I'm not entirely sure this is the right sequence for a more general patch for Qt.
Thanks to Adrian Bunk for finding the right piece of code and providing an initial patch.
