I think that we should keep alphabetical order, both systems diverged over 20 years ago and besides common ancestors decades ago, they are different. Linux adopted BSD interfaces too (like ptrace(2)).

SANITIZER_BSD has no point in my opinion. Pretending that something is BSD-flavor and defining it as a standard is a losing battle, we all are struggling to be compatible with POSIX. Old interfaces over they years were refactored, deprecated, replaced, abandoned, reinvented etc. We will end up with `SANITIZER_BSD && !SANITIZER_OPENBSD` and similar.
