So, it happens that with the Kodi version we have, 17.6-Krypton, nothing
in Kodi actually links with readline:

    $ grep -r libreadline.so.8 output/target
    Binary file target/usr/lib/python2.7/lib-dynload/readline.so matches
    Binary file target/usr/lib/libreadline.so.8.0 matches
    Binary file target/usr/bin/sqlite3 matches

Kodi itself is linked to libpython2.7.so.1.0, but does not seem to
actually import the readline module at runtime (as far as I could see).

So: applied to master, thanks.

When we bump kodi to 18.x-Leia, any remaining problem will resolve by
itself as Kodi is now GPL-2.0-or-later.

Regards,
Yann E. MORIN.
