OLD_ICONV has long been needed by FreeBSD so config.mak.uname defines it unconditionally. However, recent versions do not need it, and its presence results in compilation warnings. Resolve this issue by defining OLD_ICONV only for older FreeBSD versions.
Specifically, revision r281550[1], which is part of FreeBSD 11, removed the need for OLD_ICONV, and r282275[2] back-ported that change to 10.2. Versions prior to 10.2 do need it.

This is a follow-up to [1] which encapsulates Jonathan's proposed change as a proper patch. I made Jonathan as the author since he did all the hard research and formulated the core of the change (whereas I only reported the issue and extended the version check to correctly handle FreeBSD 10.0 and 10.1). Jonathan's sign-off comes from [1].
