Add ci test to run against minimal gcc version we support

We currently support gcc 9 as a minimum compiler version.  We should run
at least one ci job against that minimal version to make sure we don't
break anything.

Most notably this will help us catch errors if we attempt to use
intrinsics that aren't supported by that compiler.
