I'm not sure about this - I'm still finding my way around some things
here, but I'm pretty sure we do need iconv_open(3) in libiconv. Does it
compile with this change?

I'm going to forward this as a possible change to the mailing list at
libxml-devel@rubyforge.org .

If you are passing --with-xml2-<whatever> settings, you should be fine
to comment-out the lines that run those scripts (for both CFLAGS and
LDFLAGS). If that works for you I'll fix it with a default to the
dir_config and commit it.

(I'm still finding new stuff in mkmf so if I'm missing anything, please
let me know :))
