Whelp, I guess that explains why CI didn't tell me off for breaking the
self-contained headers. The pattern matching works, I didn't see any
residue after a make clean, and git status is not swamped with the
artifacts. Single object build still works. O=_build still works
(O=_build -j10 did not, hopefully that is not significant???)
Everything looks (mostly) in order,
