Yeah. I agree with Andrew that we want output that is more modular,
not less so. But we do need to find a way to have less knowledge
hard-wired in the buildfarm client script.

The obvious place for "somewhere" is "the main source tree", so I
doubt your second suggestion is better than your first. But your
first does seem like a plausible way to proceed.

Another way to think of it, maybe, is to migrate chunks of the
buildfarm client script itself into the source tree. I'd rather
that developers not need to become experts on the buildfarm client
to make adjustments to the test process --- but I suspect that
a simple script like "run make check in these directories" is
not going to be flexible enough for everything.
