Qt5 Build Error in MSYS/MinGW environment

[Paul H.]

Hello. I am trying to build QT 5.4.2 in a MSYS shell, using this toolchain: x86_64-4.9.2-release-win32-seh-rt_v4-rev3. I get the following error:
"as.exe: .obj/release/qopenglversionfunctionsfactory.o: too many sections (35780)
Fatal error: can't close .obj/release/qopenglversionfunctionsfactory.o: File too big"

This is my configuration command:
../qt5/configure -prefix /local64/qt5 -platform win32-g++
-debug-and-release -opensource -no-icu
-opengl desktop -confirm-license -nomake tests -nomake examples
-no-openssl
I have tried this on my Windows 7 desktop as well as my WIndows 8.1 laptop, and get the same error. I have successfully built this version in a windows command shell with the same toolchain, with icu, openssl, and qtwebkit. I just wanted to see if I could build it in an MSYS shell. Anybody here know why I am getting the error mentioned above?
Thank you.
Paul

I have the same problem with Qt 5.8 and MinGW64 6.3:
