While I'd quite like to have the XML support code, I don't need it for
my current testing.  I've not studied expat enough to be sure how to
re-write the source code, so here's a patch that changes configure to
test for what we currently need.  This patch is redundant if the sources
are fixed.

I don't currently have autoconf-2.59 on my machine, so I've tested this
by cut-n-paste.  It might be wise for someone with the right autoconf
version to verify this patch and then apply it if appropriate.
