Как я могу собрать Qt с оптимизацией по времени соединения, используя mingw-w64?

Сборка Qt 5.12.3 с mingw-w64 с использованием g ++ 8.1.0 работает хорошо. Но как только я добавляю параметр -ltcg к параметрам configure, я получаю ошибки сборки.

Настройка вызова выглядит следующим образом: 

../qt5/configure -prefix ../qt5Install -release -recheck-all -ltcg -confirm-license -opensource -platform win32-g++ -opengl desktop -nomake examples -nomake tests -system-freetype -I /c/Libraries/OpenCascade/3rdPartyMingw64/freetype-2.6.3-mingw-64/include -L/c/Libraries/OpenCascade/3rdPartyMingw64/freetype-2.6.3-mingw-64/bin -skip qtconnectivity -skip qtdeclarative -skip qtlocation -skip qtmultimedia -skip qtquickcontrols -skip qtquickcontrols2 -skip qtsensors -skip qtwebsockets -skip qtwinextras -skip qtwebchannel -skip qtwebengine

Кому-нибудь удалось собрать Qt с оптимизацией по времени соединения с использованием mingw-w64? В чем прикол?

Кажется, что я нашел способ собрать Qt с оптимизацией по времени компоновки: изменив файл mkspecs/win32-g++/qmake.conf, установив строку флагов компоновщика в

QMAKE_LFLAGS_LTCG = $$QMAKE_CFLAGS_LTCG -Wl,-allow-multiple-definition

делаетсборка Qt удалась с помощью mingw-w64.Я зарегистрирую отчет об ошибке Qt для этой проблемы оптимизации во время соединения.

Оптимизация во время соединения уменьшает средний размер библиотеки Qt здесь на 9%.Единственный недостаток, который я вижу, заключается в том, что библиотеки Qt5OpenGL.dll и Qt5Xml.dll слегка растут на 0,3% и 3,0%.
