the following series need merge, they remove some old rte atomics and
normalize the use of gcc builtins to set the tree up to be more easily
converted to stdatomics.

https://patchwork.dpdk.org/project/dpdk/list/?series=27530
https://patchwork.dpdk.org/project/dpdk/list/?series=27552

please review the linked series if you have time, since the impact of
the changes may be broad it would help David and Thomas.

as soon as the above series are merged i will begin submitting the
actual stdatomics series for review.

thanks!
