[Discuss-gnuradio] Empty volk directory when I git gnuradio

[Chris \"Gump\" Graves]

Looks like some kind of link or something is broken when you try to GIT
gnuradio.  The build fails as volk will not build, and the volk sub-
directory is empty.  I did successfully GIT volk directly and clone it
to it's sub-directory in gnuradio, and the build then went fine.

Just throwing that out there so someone can try to fix it or get it fixed.
