This is not a recent change.  It's been happening since August 2017.  It is
automatically enabled if you're building the code from a git clone instead
of a tarball.

I'd say that once we get some feedback about whether bug #66 is still a
problem (Xastir crashing when zooming in and out with OSM maps enabled), 
we're probably ready to start kicking release 2.1.2 out of the nest.  Are the
NWS and other download scripts up to date?  For 2.1.0, NWS changed the download
site really soon after the release, so perhaps this is always going to be
a moving target.
