I think you are onto something, after completely removing Xen I cannot
compile 4.0:
Wl,-O1 -L../../tools/libxc
-lxenctrl -L../../tools/libxc
-lxenctrl -o libvhd.so.1.0.0 -luuid libvhd.o libvhd-journal.o
vhd-util-coalesce.o vhd-util-create.o vhd-util-fill.o
vhd-util-modify.o vhd-util-query.o vhd-util-read.o vhd-util-repair.o
vhd-util-resize.o vhd-util-revert.o vhd-util-set-field.o
vhd-util-snapshot.o vhd-util-scan.o vhd-util-check.o relative-path.o
atomicio.o ../../lvm/lvm-util.o
/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/../../../../x86_64-pc-linux-gnu/bin/ld:
cannot find -lxenctrl
collect2: ld returned 1 exit status
make[6]: *** [libvhd.a] Error 1
make[6]: Leaving directory
`/var/tmp/portage/app-emulation/xen-tools-4.0.0/work/xen-4.0.0/tools/blktap2/vhd/lib'
make[5]: *** [subdir-all-lib] Error 2
Which makes me think that some part of 4.0 was compiled against 3.4.2...
