+configure.in: use pkg-config for libpcap detection
+
+The detection of libpcap was based in ${prefix}, which doesn't make
+sense in a cross-compilation context and can cause host leakage into
+the target build.
+
+So instead, let's use pkg-config to detect libpcap, since it is anyway
+already use in this configure.in to detect libglib.
