Re: [PATCH 05/15] t/Makefile: optimize chainlint self-test

>Rather than running `chainlint` and `diff` once per self-test -- which
>may become expensive as more tests are added -- instead run `chainlint`
>a single time over all tests bodies collectively and compare the result
>to the collective "expected" output.
