svn commit: r270951 - in head: share/mk usr.sbin/auditdistd

New Revision: 270951
URL: http://svnweb.freebsd.org/changeset/base/270951

Log:
  Add -Wthread-safety to WARNS=6.
  
  While there, add a NO_WTHREAD_SAFETY flag that can be used to disable
  this specific warning flag. Disable it for auditdistd. We can easily
  patch up auditdistd to have the right annotations to build, but as
  auditdistd is intended to be portable across other operating systems,
  it's not worth the effort.
