This should be xen-3.1.3/build-linux-2.6.18.8-xen_x86_32 then the rest
of your commands should work OK.

You will need to run "make mrproper" in xen-3.1.3/linux-2.6.18.8-xen to
undo what you did already.

The issues is that the Xen build system uses out of tree builds (the O=
in the output below) so source is in linux-2.6.18.8-xen and objects are
in build-* (this saves having multiple copies of the source).

You have caused the source tree to be used as an object tree which leads
to the error you have observed.
