Aha I'd been puzzling over why people had been seeing this but I'm not! 

This very likely is to do with Debian and Ubuntu's transition to
"multiarch" which has necessitated removing the old compatibility
symlink /usr/lib64 -> /usr/lib.

lib64 is a RPMism which doesn't really apply to Debian and derivatives
and therefore you need to tweak your Xen config before building. I use
the following local configuration patch (I should probably do the
equivalent in .config):

Can you try a fresh build with this applied and see if that helps.

If it does then I shall update
http://wiki.xen.org/wiki/Compiling_Xen_From_Source with this
information!

Roger -- is there any way we could automate this via autoconf for 4.2?

Ian.
