Except that v1 didn't EXACTLY match virnetdevbridge.c.

This is the missing piece:
diff --git i/configure.ac w/configure.ac
index 4f2a7e9..4d6698d 100644

I've now tested fresh checkouts on RHEL5, RHEL6, Fedora 19, and FreeBSD;
since all of them are able to pass configure, I'm going to repost the
patch as a v2; but since the build failed last time around when invoking
the build-breaker rule, this time around I'll wait for a review.
