Our osx-gcc job explicitly asks to install gcc-13. But since the GitHub
runner image already comes with gcc-13 installed, this is mostly doing
nothing (or in some cases it may install an incremental update over the
runner image). But worse, it recently started causing errors like:
==> Fetching gcc@13
==> Downloading https://ghcr.io/v2/homebrew/core/gcc/13/blobs/sha256:fb2403d97e2ce67eb441b54557cfb61980830f3ba26d4c5a1fe5ecd0c9730d1a
==> Pouring gcc@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink bin/c++-13
Target /usr/local/bin/c++-13
is a symlink belonging to gcc. You can unlink it:
brew unlink gcc
which cause the whole CI job to bail.
I didn't track down the root cause, but I suspect it may be related to
homebrew recently switching the "gcc" default to gcc-14. And it may even
be fixed when a new runner image is released. But if we don't need to
run brew at all, it's one less thing for us to worry about.

I don't think this was due to anything on our side. I tried to re-run
versions of git.git which had previously passed and ran into the same
issue.
I'd like to report that this let me get a successful CI run, but I'm
running into the thing where osx jobs seem to randomly hang sometimes
and hit the 6-hour timeout. But I did confirm that this lets us get to
the actual build/test, and not barf while installing dependencies.
