Hi, all:
i back port a patch which make qemu depends on util directory.
so i correct its dependency by applying a patch. but another error occur.
the patch is :

When linking with libvirt_util, you also want to link with
libvirt_probes.o. However, conditionally:
if WITH_DTRACE_PROBES
libvirt_driver_qemu_impl_la_LDADD += libvirt_probes.lo
endif WITH_DTRACE_PROBES
However, libvirt-driver-qemu-impl.la is going to be
libvirt-driver-qemu.so which is eventually loaded by the daemon which
already has libvirt_util (via libvirt.so). So what I'm saying is that
you should not need to link with libvirt_util in the first place.
