Doe we want this?
I think most GPLv2 code carries the clause:

"This program is free software; you can redistribute it and/or
modify it under the terms of the GNU General Public License
as published by the Free Software Foundation; either version 2
of the License, or (at your option) any later version."

Yet currently virtually all of these have GPL or GPLv2 as LICENSE

v2+ versions:

enblend/plotutils_2.6.bb:LICENSE = "GPLv2+"
ffmpeg/ffmpeg_svn.bb:LICENSE = "GPLv2+"
gnome/epiphany_2.30.2.bb:LICENSE = "GPLv2+"
gpe-package/gpe-package_0.4.bb:LICENSE = "GPLv2+"
libftdi/libftdi_0.18.bb:LICENSE = "LGPL GPLv2+linking exception"
libnfo/libnfo.inc:LICENSE = "LGPLv2+"
lzo/lzo2_2.03.bb:LICENSE = "GPLv2+"
raw-tools/exiv2_0.20.bb:LICENSE = "GPLv2+"
sysvinit/sysvinit_2.86.bb:LICENSE = "GPLv2+"

udev/udev_151.bb:LICENSE = "GPLv2+"
udev/udev_154.bb:LICENSE = "GPLv2+"
