Normally I'm loath to force push, but in this case I had a giant commit that shouldn't be there.

From there it was a matter of picking a poison: a giant revert commit or a force push. I chose the latter.

The content is entirely different and doesn't seem to match the title. Is this right?

Yes, this PR is now a single concern where the title is congruent with the single(tiny) commit.

"Makefile log info": This matches the commit: tweak logging info so that the number of threads specified in "-threads" is logged into .log.
