[bug#38650] [PATCH] gnu: adds hackrf

[Christopher Howard <christopher.howard@qlfiles.net>]

I have asked many times about the new release over the last few months,
and each time hackrf team says it is a week or so away. But their last
git commit was in February. Requesting to please proceed with the
latest commit as represented in this patch. I have added information to
the description as requested.

Using the old 2018 release would be unsatisfactory due to an annoying
bug related to maintaining connections to hackrf devices.

As an additional motivation for adding this, I believe you need
libhackrf installed to use hackrf with gnuradio, through the osmocom
interface. (I'm not at the moment quite clear on what exactly you have
to enable in the gnuradio package definitions to link those together.)
E.g., https://packages.debian.org/stretch/gr-osmosdr
