libvirt.git commit 2621d48f00 removed the last traces of gnulib, which
also removed the '--no-git' option from autogen.sh. Unknown options are
now passed to the configure script, which quickly fails with

  configure: error: unrecognized option: `--no-git'

Remove the gnulib handling from ts-libvirt-build, including the '--no-git'
option to autogen.sh. While at it remove configure options no longer
supported by the libvirt configure script.

The only change from V1 is adding Ian to cc.

I have poor perl skills, but hopefully this fixes the latest build
failures of the libvirt test project, e.g.

Harmf.  Thanks for looking into this and trying to fix this mess.

I think there is a problem with your patch, which is that 2621d48f00
is recent enough that we might want still to be able to build with
earlier versions.

Is there an easy way to tell (by looking at the tree after checkout,
maybe) whether to do the old or the new thing ?

Your perl code looks good to me for what it is trying to do.

Thanks,
Ian.

Ah, good point.

There would be no gnulib directory in a tree checked out after commit 
2621d48f00. Another option is to check for the 'bootstrap' script in the root of 
the tree, which was removed by 2621d48f00.

I'm afraid my perl is too weak to quickly hack something up to support both pre 
and post gnulib builds :-(. I'll add this task to my list if you don't have time 
for it.

Regards,
Jim
