rillig 72c440a8cd converters/libiconv: allow to skip --with-libiconv-prefix
There are several GNU configure scripts that don't support this option.
These packages can be found by setting GNU_CONFIGURE_STRICT=yes in
mk.conf. To allow these packages to build nevertheless, packages have to
skip this option explicitly, for backwards compatibility.
