[dpdk-dev] [PATCH 2/2] net/pcap: fix cross compilation

[Bruce Richardson <bruce.richardson@intel.com>]

The detection of pcap as a dependency involves invoking pcap-config to get
parameters - something not possible in a cross-compilation environment.
Therefore we need to just look for the presence of the library in a
cross-compilation environment and assume if the library is present we can
compile and link against it.
