One reasonable option for backporting is to add the definition of
check().  It's a really simple shell function:

    check() {
        echo "$@"
        AT_CHECK(["$@"])
    }

If you're only changing a few tests and you didn't want to update
ovn-macros.at (I see that the commit that added check() is pretty big),
then you could just add that definition to each one.
