[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.  Compatibility between non-OCAML and OCAML
builds needs to be maintained since updates might make cross-building of
OCAML possible or an installation might replace one with the other.

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.
