iOS support demands iOS 9.x capabilities preventing builds for older 8.x devices

Steps to reproduce the problem:

1 Install Qt 5.6 beta on a Mac running El Capitain and Xcode 7.2
2 In Qt Creator, create a new QtQuick project for Qt 5.5
3 Build the app
4 Connect an iOS device e.g. iPad Mini2 running iOS 8.1.1
5 Launch the app on the device
6 Observe the following in the Application Output window:

Starting remote process.
QML debugging is enabled. Only use this in a safe environment.

Run ended.

Note: The same is not true in Qt 5.5.1 with the same OS, Xcode and iPad Mini2. That app builds and runs succesfully.
