Daniel P. Berrange 1bfb47dfe6 Make ESX & Hyper-V code generator safe with parallel builds 
If from a clean GIT checkout 'make -j 8' is run, the ESX
and Hyper-V code will be generated multiple times over.
This is because there are multiple files being generated
from one invocation of the generator script. make does not
realize this and so invokes the generator once per file.
This doesn't matter with serialized builds, but with
parallel builds multiple instances of the generator get
run at once.

Prevent this using a timestamp file to control generation,
as was previously done for the python bindings in commit

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
