Re: porting OOT to gr3.8 Make failure

Just FYI, I tried the latest VOLK with your patch, but that doesn't help
if VOLK is built with ORC. It looks like libvolk.so is required by
libgnuradio-runtime.so (there's one volk_get_alignment() call in
gnuradio-runtime) and libvolk.so requires liborc-0.4.so.
