Hi Ferruh,

Thanks for taking a stab at this.  I think there isn't such a simple
solution, because this change causes an ABI failure (for some reason)
like:

  [D] 'function int rte_power_guest_channel_send_msg(channel_packet*, unsigned int)'    {rte_power_guest_channel_send_msg@@DPDK_21}

I guess we might need the full type of aliasing solution documented in
Ulrich Drepper's paper https://www.akkadia.org/drepper/dsohowto.pdf

That will really need someone who knows what the symbols should look
like based on the ABI / API for the different versions.  WDYT?
