There a gotcha here. The manual states, in chapter 12.3:

    Buildroot [is] released under the GNU General Public License,
    version 2 or (at your option) any later version.

So, we have to clarify: is it GPLv2 or GPLV2+ ?

It's too late today for me to go digging; I'll do that tomorrow. Just
rmind me before the end of the week if there's not feedback from my part
on this topic.

Until then, NAK.

Here's an alternative proposal, to replace both sentences:

    Buildroot comes with its own license, reproduced below.

    Buildroot also bundles patch files, which are applied to the
    sources of the various packages. Those patches are not covered
    by the license of Buildroot. See those individual packages for
    their license (running 'make legal-info' after your build may
    help).

Yann E. MORIN.
