Using gnulib-tools' --lgpl=2 option fixes this.
That will cause the copyright notices to be rewritten.
However, that currently excludes *all* of the unit tests, because
these tests rely on LGPLv3 modules.  So the easiest solution
(though it's unfortunate for both libvirt and gnulib) is to give
up those unit tests: i.e., to remove the --with-tests option below.
And without the tests, there's no need for the three --avoid= options:

diff --git a/bootstrap b/bootstrap

   --source-base=gnulib/lib	\
   --tests-base=gnulib/tests	\

That empties the gnulib/tests directory of all its *.c files,
but I'd like to leave it (with just Makefile.am), in the hopes
we can work out a compromise that lets us use the tests again.

I'll prepare a patch along these lines.
