Subject: [PATCH] ci: fix GCC install in the GCC OSX job

A few days ago Travis CI updated their existing OSX images, including
the Homebrew database in the xcode10.1 OSX image that we use.  Since
then installing dependencies in the 'osx-gcc' job fails when it tries
to link gcc@8:

  + brew link gcc@8
  Error: No such keg: /usr/local/Cellar/gcc@8

Apparently 'brew link gcc' works, so let's do that then, and fall back
to linking gcc@8 if it doesn't.
