[Buildroot] [git commit] libpcap: omit -rpath from pcap-config

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=be995fbb403653336b5929adcd6e90b1ebbbe604
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

For target processes the libraries are always in their usual location under
/lib and /usr/lib. It doesn't make sense to add RPATH tag pointing to host
build directory to programs using libpcap. This commit changes V_RPATH_OPT in
pcap-config to remove -rpath from its output.
