[Buildroot] [git commit] package/gnutls: make the OpenSSL compatibility library optional

commit: https://git.buildroot.net/buildroot/commit/?id=d4c12d6bcdfc2813dfac3d207d980e0497d33f5d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add a BR2_PACKAGE_GNUTLS_OPENSSL option, disabled by default since it is
not used by any package that depends on gnutls.

The library is licensed under GPLv3, which can be a problem for embedded
systems due to the so-called anti-tivoization clause.

simply append to them]
