commit: https://git.buildroot.net/buildroot/commit/?id=85a28f392783cf6b80881be02609c6df460e1dab
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

libpcap can depend on other libraries like libusb and doesn't support
pkgconfig, so add those libraries to LIBS when building statically.
Fixes:
