Comment (by strk):

 MacOS seems happy with SFCGAL backed orientation test:
 https://github.com/postgis/postgis/actions/runs/24517797174/job/71666698668

 Except newer SFGAL changes that algorithm to delegate to GDAL
 (https://gitlab.com/sfcgal/SFCGAL/-/commit/79147457a6532b528b858eb62bcd66cc49c3b057),
 effectively breaking a lot of tests
 (https://github.com/postgis/postgis/actions/runs/24517797133/job/71666698732)
