Honestly, I only was caring about 'make tools/tmon' but noticed other
things were broken. I'd be OK if we didn't support building from the
top-level directory (it's just confusing things here), but since we
advertise the feature, it'd really better work!

Yeah, I'm not likely to spend time on an updated fix real soon. Consider
my patch a bug report, if the suggested fix doesn't work out. I'm not
much of a build system expert here.
