Subject: Merged r9433:9527 from features/gr-usrp2 into trunk. Adds usrp2 and
gr-usrp2 top-level components. Trunk passes distcheck with mb-gcc installed,
but currently not without them. The key issue is that when mb-gcc is not
installed, the build system skips over the usrp2/firmware directory, and the
firmware include files don't get put into the dist tarball. But we can't do
the usual DIST_SUBDIRS method as the firmware is a subpackage.
