Change subject: Add osmocom-build-old-tags-against-master.sh
......................................................................

Add osmocom-build-old-tags-against-master.sh

Build old releases of Osmocom programs and libraries against
"master of the day" to detect breakage.

This initial configuration builds the last three release tags of the
Osmocom repositories against master, but specific tags could be
configured as well if needed.
