There was an issue raised (long ago) about this in the anitya tool
(which generatees the DB at r-m.o):
    https://github.com/release-monitoring/anitya/issues/374

So, the version strings we get from r-m.o should no longer have a
leading 'v' anymore.

Yet, in our FOO_VERSION, we in Buildroot may still have those leading
'v'. So, we should try to compare the versions as-is, and then remove
out leading 'v' and compare again. ot sure of the exact heuristic,
though...
