+Remove libpcap compile tests to fix cross-compiling
+
+These compile tests are run on the host machine which may have or may
+not have libpcap installed, so we are relying on the host machine to
+determine if we have to stop the build process due to a missing pcap
+library. Given that Kismet already depends on libpcap we can be sure
+that library will be installed in our target. So, for these two reasons
+we can remove these compile tests from the configure script.
