Do not archive NFSv4 ACLs on Mac OS X by default.
This avoids wrtiting ACLs to tar files twice. Preferred method is
via copyfile(3) (tar option --mac-metadata). If user wants to create
archives with portable NFSv4 ACLs only (SCHILY.acl.ace header with no
GUID data) the --acls and --no-mac-metadata options must be specified
on the command line.
In the manual page be more specific which types of ACLs are stored
with --acls and --mac-metadata options.
