[libvirt] Patch to include arm variants in virsh capabilities

Hey folks, I got an android and wanted to set up an armel debian vm to test out some code. I had to launch it directly with qemu-system-arm, though, since virsh didn't have an arm option to select. This is a patch against the debian version of the source after applying debian-specific changes. If you'd like a patch against mainline, I'd be willing to do that. http://karma.colliertech.org/~cjac/tmp/add-arm.patch Cheers, C.J.
