    Windows 10, GCC 10.2.0 MinGW-w64 8.0.0
the following tests passed on new mingw-w64 8.0 but actually cannot build. (mingw-w64 7.0 cannot pass, so no issue)
- $\src\qtdeclarative\config.tests\d3d12 (passed, but missing fxc.exe for shaders)
- $\src\qtmultimedia\config.tests\wmf (DirectX header partial completed)
lastest GCC/MinGW-w64 I download from here https://github.com/asanoic/asanoic-mingw64-build
