[libvirt] [PATCH] spec file enhancements for minimal "client-only" build

[Ben Guthro]

Attached is a patch to add some additional options to the spec file, 
allowing for more flexibility when building.
With this patch, it allows you to build a "client-only" version of 
libvirt for machines that may have an interest in communicating over the 
remote driver, but do not have a hypervisor themselves.

It enables command line overrides of control variables for the build
eg:
rpmbuild $(RPM_FLAGS) --nodeps \
        --without xen \
        --without xen_proxy \
        --without qemu \
        --without openvz \
        --without lxc \
        --without polkit \
        --without libvirtd \
        --without avahi \
        --without sasl \
        --without python \
        --without devel \
        -ta --clean libvirt*.tar.gz
