* <https://www.freebsd.org/doc/en/books/porters-handbook/using-iconv.html>
* says that libc has iconv since 2013, in 10-CURRENT. FreeBSD man-pages
* shows it included in 10.0-RELEASE. Writing this in 2017, 10.3 is the
* oldest supported release, so we should assume non-libiconv by default.
* (Actually, people still using old releases past EOL; we shouldn't support
* them but I don't want to deal with howls of complaints because we dare
* to not support the unsupported, so guard this on FreeBSD 10+)
*
* Thus we no longer override iconv.
*
* However, if libiconv is installed, and anything adds /usr/local/include
* to include-path (likely) then we'll get that. So define a variable
* which makes the libiconv try to not interfere with OS iconv.
