The headers are there, so it gets detected and configured, it's just that on
some slightly older distros (such as ubuntu 12.04, which is what's in
Travis-CI), you can't install the libusb-dev libraries for both :i386 and
:amd64  at the same time.

So if you build something, tcpdump, my uml_netjig, etc. that needs -lpcap,
you can't build it for both -m32 and -m64 without rejigging libraries.

Since I don't need pcap-usb support, and I'm building libpcap from source
anyway as I need the latest one, I'm happy to simply turn off usb support.
