ACK to this patch btw, it does solve the problem in SuSE distros
where
device-mapper-devel is missing pkgconfig file. But the problem is
really a bug in the devel package, so will this workaround be committed
to libvirt configure script?
Afaics, the opensuse patch has been sent and is now being reviewed. So
hopefully this patch will not be needed (at least not for opensuse).
