Somehow or another, I previously had missed `BUILD.mk` files. In the process I found a few straggler cases where the modeline was different from the file, including one very involved manual fix where a file had been treated like it was ts=2 and ts=8 on separate occasions. The commit history in the PR shows the gory details; the BUILD.mk was automated, everything else was mostly manual.
