Hmm, I guess my vision is that in typical usage all the library/pkg
tests will always default to 'check', so we'll test them all and report
success/failure at the end. If you're actually using --with-sasl=yes,
then I'm assuming you've looked at the configure script and decided
what you need upfront.

Ok, I've made changes 1->4 and pushed
