[Buildroot] [PATCH 00/11] Fix license incompatibility with readline

[Peter Korsgaard <peter@korsgaard.com>]

Hi,

We have a number of packages where we (optionally) link with readline,
even though the license of the package isn't compatible with the
license of readline (GPL-3.0+), E.G. for packages licensed under
GPL-2.0 only.

This series aims to fix that. I've tried to review the entire tree,
and this is what I found:

Linking with the older bundled copies of readline in mariadb &
oracle-mysql, isn't very nice - But there is not much we can do
besides packaging the old GPL-2.0+ version of readline, and that then
leads to issues withe file conflicts when both readline versions are
enabled.

I haven't been able to find a license exception for nftables (it does
have one for openssl though), but I do see that E.G. Debian also links
it against a modern readline:

https://packages.debian.org/buster/nftables

Similar for open-lldp. The upstream website seems to be down, so
perhaps the package should simply be dropped?

I have mailed ytree upstream to clarify licensing, but so far without
any reply.
