    misc: syslog: Move SYSLOG_NAME to USE_MISC (BZ #16355)
    
    There is no easy solution as described on first comment in bug report,
    and some code (like busybox) assumes facilitynames existance when
    SYSLOG_NAMES is defined (so we can't just remove it as suggested in
    comment #2).
    
    So use the easier solution and guard it with __USE_MISC.
