MPM event was picking up the headers but not linking with libserf, causing unresolved symbol errors. Now build MPM event with or without serf support depending on --with-serf being specified or not. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@954273 13f79535-47bb-0310-9956-ffa450edef68
