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.
