meta-openembedded/meta-networking/recipes-support/ntop/ntop/ntop_configure_in.patch

1)add --with-pcap-config option to use libpcap's pcap-config
2)add AC_CHECK_LIB if user didn't specify PCAP_ROOT and pcap-config
  put it before host check to make cross-compiling easier.
  pcap doesn't need extra include and libs so it is fine.
3)remove old rrd configure code but use pkg-config to config rrd
  rrdtool should have the pkg-config file installed.
4)fix python-config
5)change AC_TRY_RUN to AC_COMPILE_IFELSE for pthread_rwlock_t checking
6)fix a net-snmp-config bug
