This issue would be present since the beginning.
Why do we need different sections libnl_3.2.* instead
of one libnl_3?
What is wrong with:

>>>

libnl_ at MAJ_VERSION@ {
global:
        *;
local:
        _nl_socket_generate_local_port_no_release;
        _nl_socket_is_local_port_unspecified;
        _nl_socket_used_ports_release_all;
        _nl_socket_used_ports_set;
};

<<<

(MAJ_VERSION being "3")
