- Add DOCS option.

- When the NLS option is enabled the configure script looks for iconv_open()
and libiconv_open() functions in libiconv before trying libc. This means
that on FreeBSD 10 proftpd depends on converters/libiconv when it is
installed but it should use iconv from libc instead.
To fix this add ac_cv_lib_iconv_iconv_open=no and
ac_cv_lib_iconv_libiconv_open=no to CONFIGURE_ARGS to bypass those
configure tests when ICONV_LIB is empty.
- Remove references to -lintl. The configure script detects it correctly.
