Presumably this text is a leftover from before 8.2:

Author: Bruce Momjian <bruce(at)momjian(dot)us>
Branch: master Release: REL8_2_BR [9e66c3e6f] 2006-02-04 01:00:02 +0000

Move thread_test directory from /tools to /test so source-only tarballs
have the directory for the configure test.

It probably worked okay on most platforms before v12 (96bf88d52).
We could put back the text and fix where it pointed to, but on the
other hand I'm not sure it's worth the trouble. Obviously nobody
has paid any attention to that para in a long time.

Yeah, I think we could just nuke that line.
