You relaxed pipe2 but not binary-io.  Since the former requires the
latter, this introduces a licensing conflict.  And since the latter only
includes a single .h file that just wraps system functions, and given
your above agreement to my broader question, I've gone ahead and pushed
the obvious followup:

        binary-io: relicense under LGPLv2+
        * modules/binary-io (License): Relax to LGPLv2+.
        Requested for libvirt, and required by pipe2.
