Ok, I think I got it to work.  See attached Dockerfile.

Use with (fixup the path to the source tree in the `-v` flag):

$ docker build -t opensuse-gdb-mingw-w64 .
$ docker run -v /home/simark/src/binutils-gdb:/src -it opensuse-gdb-mingw-w64:latest
# ./build.sh

Of course, since you likely have a tumbleweed system already, you can
simply install the required packages on that machine.
