I would see a point in making them buildable in a standalone
fashion if

  1) we installed them, eg. under /usr/share/doc/libvirt/examples
  2) we also installed, for each of them, a plain Makefile that
     calls $CC and pkg-config as seen above

Until that's the case, the gnulib dependency makes complete sense to
me, because you're not going to install libvirt using your package
manager, then clone the git repository and figure out yourself how
to compile the examples, just to poke around a bit.

Anyway, I've noticed that the apparmor/ directory contains files
that we end up installing on the system in non-documentation
directories, which feels all kinds of wrong. Am I missing something,
or should we move that stuff somewhere else?
