[Qt-creator] Xcode 8 woes

[Jason H]

FYI for those going through the Xcode upgrade

So Apple upgraded me to xcode 8.

I had 5.6.0 installed, and my project would not build. I added 5.6.2 kit to the project, set make args to "-j 8" and it reliably crashed. (Thread dump below)
Eventually I work it through getting that set, including accepting the license agreement
I get a message:
 Project ERROR: Xcode not set up properly. You may need to confirm the license agreement by running /usr/bin/xcodebuild.
Turns out I have to run xcode-select --install

Then it still tried to qmake using 5.6.0. I had to remove the 5.6.0 kit from Creator, then it was able to build again.
