x86_64-w64-mingw32 7.3.0
Description
When cross-compiling Qt 5.12.0 Alpha using x86_64-w64-mingw32 7.3.0 as provided by Ubuntu 18.04 (as well as Debian Testing & Unstable), the cross-compilation fails due to x86_64-w64-mingw32/lib/libdwmapi.a not having DwmInvalidateIconicBitmaps symbol exported. Only 64-bit MinGW is affected, the 32-bit one – i686-w64-mingw32 – does export DwmInvalidateIconicBitmaps symbol in its i686-w64-mingw32/lib/libdwmapi.a.
There is a similar bug report but of using MinGW on Windows instead of Linux, and the reporter in their last comment claims that the issue was fixed in MinGW 7.3.0, which is clearly wasn't fixed in 7.3.0, at least from my experience. https://bugreports.qt.io/browse/QTBUG-63627

("Unknown module(s) in QT: quick-private" is reported in a separate bug report: https://bugreports.qt.io/browse/QTBUG-70489)
To reproduce, run the attached build_qt.sh script on Ubuntu 18.04 with x86_64 as the argument:
./build_qt.sh x86_64
If you prefer using Docker:
mkdir build mv build_qt.sh build sudo docker run --rm -v "$PWD/build":/build ubuntu:18.04 /bin/bash /build/build_qt.sh x86_64
