Vagrant-libvirt: Nokogiri upgraded in Vagrant 1.9.4

[jcf]

Installation of vagrant-libvirt via vagrant plugin install vagrant-libvirt and the longer Arch Linux version fail with the following error:

It looks like Vagrant upgraded its version of Nokogiri here.

This is the longer recommended installation command for Arch Linux that doesn't make a difference.

CONFIGURE_ARGS='with-ldflags=-L/opt/vagrant/embedded/lib with-libvirt-include=/usr/include/libvirt with-libvirt-lib=/usr/lib' \                                    ⏎
  GEM_HOME=~/.vagrant.d/gems GEM_PATH=$GEM_HOME:/opt/vagrant/embedded/gems PATH=/opt/vagrant/embedded/bin:$PATH \
  vagrant plugin install vagrant-libvirt

Workaround mentioned at #828 (comment) worked for me
