Hi Ed,
Since it works for me at Qt-5.4.2,
please find more details:

1. Go Preferences->Build&Run -> Compilers
2. Select Add;
3. In the form fill the following:

Name: iphoneos-clang
Compiler path: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
Platform codegen flags: -arch armv7
Platform linker flags: -arch armv7

After setting  "-arch armv7" flags, the correct arm ABI is selected
and you do not need there nothing manually (it's set to 32-bit, that's OK).

4. Go Preferences->Build&Run -> Kits

Name - add the appropriate and clear for you name
Device type - select iOS Device
Sysroot - /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk

Compiler: select iphoneos-clang that you added;
Debugger: select some lldb, i.e. from
Qt - select the qt-version compiled for iOS arm

Mike Nelson has tested basically the same I think,
but I hope that the above step-by-step could save some your time.

Take care.
