I don't quite understand what you mean by "why not run them only once".
They are run only once...?

Maybe you mean, if (a) the make binary hasn't been rebuilt and (b) the
test script hasn't been changed, then we wouldn't need to re-run the
test?  Perhaps, but realistically I'm not sure it's worth the effort to
make this change because almost the only time we ever run these tests
is when we've rebuilt the make binary, and it's easy enough to run just
a single test if we want to.
