I am not really familiar with the internals of sysklogd, but there are
definitely newer versions available:

  https://github.com/troglobit/sysklogd/releases

Have you tried if version >= 2.0 would fix your issue ? It seems like
version 2.0 is really a major rewrite.

In any case, we would very much welcome Buildroot patches to update
sysklogd to a newer version.

Best regards,

Thomas
