config.mak.uname: resolve FreeBSD iconv-related compilation warning

Browse source 
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.
