I think you can't do without because otherwise nothing links with libubsan? The diagnostic might not be too useful though. I suppose we might be ending up throwing sanitizer stuff on the floor and getting confused somehow? We do not stream -fsanitize=.. into the lto.opts section, thus LTO wrapper doesn't know about it.
