I don't remember it well, but it looks like FreeBSD's portfile has
the same argument.
http://www.freebsd.org/cgi/cvsweb.cgi/ports/converters/libiconv/Makefile?rev=1.39

Seems that When I added some features such as +enable_cp932,
extra_encodings from FreeBSD, I introduced that argument too
just in case.

Anyway, if that argument doesn't work correctly, please feel free
to modify it. Thanks. ;-)
