Fortunately for me, the mingw-w64 development team has been very helpful. I know of at least one of the mingw-w64 developers chimes in on the binutils list, perhaps there are some of them on this list, too. I'd start with this github repo which provides patches for building GCC within an MSYS2 environment: https://github.com/msys2/MINGW-packages There are patches and pacman build scripts (pay attention to the scripts, they do some magic aside from applying patches). There is stuff there for arm cross compilers. But beware, these patches may no longer apply for GCC 7.0 as the mingw-w64 folks keep pretty current with packages they deliver. Hope this helps, Tom
