For the normal targets we can re-create builds at our leisure using the
travis docker image. Unfortunately I'm not clear on how this works for
the MacOSX build.

The best solution I can come up with is to tweak your build to dump the
.text into stdout and then look on the Travis web-page as the build
fails. I had a similar fall-back encoded when debugging the clang build,
something like:

      before_script:
        - ./configure ${CONFIG} --extra-cflags="-g3 -O0 -fsanitize=thread -fuse-ld=gold" || cat config.log

So change your local .travis.yml to:

    - env: CONFIG=""
      os: osx
      compiler: clang
      script: make -j3 || cat qemu-options.texi

and trigger a build with it.
