* Adapt hacks to new config system
* Use distinct mkspec mingw-w64-g++ rather than
patching the existing win32-g++
* Testing QML and ANGLE is on TODO list
because it hasn't been tested since quite a time
- Also fix misc issues with mingw-w64-qt5-base-static
- Also provide static libs for mingw-w64-qt5-declarative
and mingw-w64-qt5-tools (other modules are still
on TODO list)
- First approach to allow usage of static version via CMake
- Use native OpenGL by default because this version seems
less buggy and ANGLE is hard to maintain; this is also the
default choice in MSYS2-MINGW-packages and MXE
