    Merge commit 4a39d0890894 from llvm-project (by Mark Johnston):

      [libc++] Fix filesystem::remove_all() on FreeBSD (#79540)

      remove_all_impl() opens the target path with O_NOFOLLOW, which fails if
      the target is a symbolic link. On FreeBSD, rather than returning ELOOP,
      openat() returns EMLINK. This is unlikely to change for compatibility
      reasons, see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214633 .

      Thus, check for EMLINK as well.
