Fixed by https://gitlab.freedesktop.org/mesa/demos/-/commit/e67dac7e61f1
which is part of https://lists.freedesktop.org/archives/mesa-announce/2022-May/000677.html
while the latest is https://lists.freedesktop.org/archives/mesa-announce/2023-March/000712.html
which contains FreeBSD fixes (upstreamed by me) but no longer supports autotools.

Note, another case for https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271600
