I'm certainly not an expert on macOS, so I could be getting things wrong
here, but it looks like we don't ever explicitly install the gcc@8
package from Homebrew. It may have happened to be installed
automatically by Travis in the past, but they may have upgraded now that
GCC 9 has been released.

I suspect if we want to use GCC 8, we need to explicitly install it by
using "brew install gcc@8", or we can just pick the latest released GCC
by using "brew install gcc" if we like that better. We will still need
to do "brew link gcc" (or "gcc@8"), since I suspect Homebrew won't
auto-link it since macOS provides a gcc binary.
