[xml] Using libiconv

[Brian Stafford <brian stafford office-logic com>]

Hi folks,

When running configure on a system which provides iconv but also
has libiconv installed in /usr/local, linking fails complaining that
libiconv_open and related functions are not found.
This is because the configure script fails to notice that -liconv
is required in this circumstance.

The following patch fixes this
