The Xen automated build tests have discovered a built error on armhf. I
don't think it is Xen specific. Our bisector has fingered the changeset
below. I've had a skim of the git log from there to master and of the
outstanding patches on libvir list and I don't see anything which is
obviously a related fix, so I hope this is still useful/relevant.

An instance of the failure can be seen at
http://www.chiark.greenend.org.uk/~xensrcts/logs/30765/build-armhf-libvirt/info.html

The logs say:
util/virsocketaddr.c: In function 'virSocketAddrIsNumericLocalhost':
util/virsocketaddr.c:904:17: error: cast increases required alignment of target 
type [-Werror=cast-align]
util/virsocketaddr.c:909:17: error: cast increases required alignment of target 
type [-Werror=cast-align]
