BUG #12275: configure incorrectly tests libxml2 version

Perhaps it's because of the suffix on the version number?

I have 2.9.1 Debian-packaged here, and it works fine for me. config.log
says:

configure:8801: result: yes

$ dpkg-query -l '*xml2*'

I don't have the :i386 packages installed here; maybe your compiler is
picking up those instead of the amd64 ones.

P.S. I hope that the appearance of line clipping I'm seeing above is an
illusion. Perhaps the bug report textentry widget should have room for 80
character wide pastes from terminals?

No such luck, but I don't think it's all that critical anyway.

There is no version check as such in the test; it's just looking to see if
xmlSaveToBuffer() links successfully. The complaint message is worded
like that because xmlSaveToBuffer() didn't exist before 2.6.23.

I don't have the :i386 packages installed here; maybe your compiler is
picking up those instead of the amd64 ones.

That or some other link failure seems like the probable cause. Looking
into config.log to see what error messages the underlying tools printed
would probably be helpful.
