Yes, but Qt's build system does not currently handle multi-arch builds, 
so you'd have to do armv7s only (or multi-arch but with precompiled 
headers disabled). Modify QMAKE_IOS_DEVICE_ARCHS in the mkspecs's 
qmake.conf.

No. Same problem as above as far as multi arch goes (armv7 + armv7s + 
arm64), and also arm64 doesn't build and is 100% untested.

In theory yes, but there might be a few issues that you'd have to 
resolve on your way. The plan is to build with C++11, we just haven't 
gotten there. You may try it out by removing the hard-coded 
CFG_CXX11="no" in the configure script for XPLATFORM_IOS.
