[Discuss-gnuradio] New instance of build-gnuradio up

[Marcus D. Leech]

This version adds a depend of "libasound2-dev" for Ubuntu systems.  
Seems that *usually* libasound2-dev is already installed in most 
installs, but I
  had one person for whom that wasn't true.

I've also updated it to include downloads of the emerging OSMOCOM 
RTL-SDR work, which includes an RTL-SDR source module. So it downloads
  and builds from the osmocom repositories.  THese are quite small 
modules, so won't impact the build time in any significant way.  It also
  installs the "udev" rules for the relevant devices.
