qt: add support for building on iOS/OSX

There's still a number of build issues with Qt's libtool .la and pkgconfig files that have not been resolved.
1. The pkg-config files only point/link to/against the simulator versions (x86/x64 arch depending on installed Qt archs)
2. The libtool files place -framework arguments in dependency_libs rather than the more correct inherited_linker_flags.

Has been successfully tested on the iOS simulator (with a severe memory leak).

Looks good. The leaks you talk about are in Qt and independent from our code?


Did you report the pkg-config / libtool brokenness to the Qt people so they can fix their stuff?

Not sure yet.

There's this old bug for the libtool frameworks issue https://bugreports.qt.io/browse/QTBUG-2390 which I commented on.

For the iOS pkgconfig machine architecture issue: https://bugreports.qt.io/browse/QTBUG-48303

What's the status here?

Both OSX and iOS require modifications to the pkg-config/libtool files in order to build against correctly.

As I could not repoen the closed libtool bug, I created a new one :/ https://bugreports.qt.io/browse/QTBUG-48575

Qt officially does not support using the pkg-config/libtool files on iOS so getting them to modify their build setup seems unlikely.

That being said, for those that are feeling adventurous, I've pushed the required patch to build/use QT on OSX and iOS.
