qt: build using old C++ standard
'std::auto_ptr' is deprecated with gcc-6 but is used in qt4 code. So we have to build using old C++ standard to prevent build failures. qt4 is not being developed no more, so unfortunately we can't update obsolete C++ code and have to add this workaround. Fixes: http://autobuild.buildroot.net/results/54172d55f39b2fcfa5b7fb4d4ee01566678babbc/ and also Qt build for ARC.
