I needed to make a couple of more libxc to libxc/include substitutions
under tools/ocaml.
The appended patch should work.
I have also pushed:

Subject: [PATCH v5] Move xenstore and libxc public headers to include subdir

Also moves xc_dom.h to include as it is used often by other xen tools.
Use the new include subdirectories to build Xen tools and qemu-xen.

Add the old libxc include path to the programs that need it to build,
on a case by case basis and commeting that they shouldn't require
internal libxc headers to build.

Signed-off-by: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>

Changes in v5:
- fix ocaml build.
