Sometimes we want to use default cmodel other than medlow. Add a GCC

I thought Palmer had submitted an equivalent patch a while back, but I
can't seem to find it.
It looks like pre-commit testing has flagged this as failing to build on
arm/aarch64. I'm not as familiar with that system, so I don't know
exactly what it's complaining about other than the configuration step
for GCC failed.
