[libvirt] OSX Homebrew support note ;)

[Justin Clift]

Hi all,

Compiling Libvirt directly from latest git master head is now supported 
on
OSX Homebrew.  It's as simple as:

   $ brew install --HEAD libvirt
   ...
   $ virsh -v
   3.0.0

This should make development of Libvirt and related virtualisation 
things
much easier on OSX. :)

The credit for this goes to Roman Bogorodskiy and Homebrew developer
"ilovezfs" (CC-d), for adding a functional rpcgen to Homebrew so we can
generate the needed RPC bindings during the build (previously missing).

Thanks heaps! :)

Regards and best wishes,

Justin Clift
