[Buildroot] [git commit] elfutils: clarify licensing info

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=506445e9638e7568b8a756a8bc76f0077d3e57b4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

elfutils libraries are GPLv2+ or LGPLv3+, standalone programs are GPLv3+
(see the NEWS file).
Make the GPLv3+ license tag/file dependant on the programs being
enabled, and make the GPLv2+/LGPLv3+ tag more descriptive.
