Lately our GCC macOS build job on Travis CI has been erroring out
while installing dependencies with:

  +brew link gcc@8
  Error: No such keg: /usr/local/Cellar/gcc@8
  The command "ci/install-dependencies.sh" failed and exited with 1 during .

Thanks for working on this. I think that the patch below is ultimately a
better approach than what we had discussed in a previous thread [1].

I think that this may in fact be better than what we have now. If we
find ourselves wanting a newer version of, say, Git LFS, then I think
we'd be benefited by upgrading the image itself. Perhaps we should look
into that shortly, although I'm not aware of any urgency to do so (at
least as it pertains to Git LFS).

Thanks all.  Let's fast-track this fix down to 'maint'.  We left the
macOS build broken for too long.
