[Pkg-xen-devel] [PATCH 6/9] debian/rules: Setup use of noOCAML profile

[Elliott Mitchell]

This adds support for use of the "noocaml" profile
(https://wiki.debian.org/BuildProfileSpec).  This allows disabling build
of OCAML portions of Xen.  As presently there is no separate oxenstored
package, this makes due by using empty files to replace expected files.

Presently the primary expected use is to allow cross-building of the Xen
packages.  At this time cross-building for OCAML is very broken.
Hopefully it may work in future, but at this time it does not.
