Before the change to add arm to the --disable-spinlocks list the
postgres build on arm would error with:

The arm specific path in the header isn't used as base gcc does not
provide the atomic sync builtins on arm. Switch to ports gcc (which
currently targets mpcore/armv6k) to get the armv6+ atomic builtins.
ports llvm doesn't build on arm currently so that isn't an option.
