failed to build cross-compiler

I'm trying to build cross-compiler(ghc-8.4.1) but got an error.

Target platform is 32-bit windows.

Here is what I do:

1. pull docker image[1]: docker pull gregweber/ghc-haskell-dev
2. install gcc-mingw-w64-i686: apt-get install gcc-mingw-w64-i686
3. download ghc source and switch to tag ghc-8.4.1-release
4. run ./boot
5. CC=/usr/bin/i686-w64-mingw32-gcc ./configure --target=i686-w64-mingw32 --enable-unregisterised
6. cp mk/build.mk.sample mk/build.mk
7. uncomment the line: BuildFlavour = quick-cross-ncg
8. run make

Error message:

If using BuildFlavour = quick, it works well.
