Hello,
If you are really talking about hwloc, you should contact this mailing list
Hardware locality user list <hwloc-us...@open-mpi.org>
(Open MPI and hwloc are different software, even if hwloc is embedded in
OMPI).

This looks strange to me. We do not use atomics in hwloc at all. Are you
really configuring hwloc and not Open MPI ?

We don't have permanent access to such a platform but it has been tested
(and successfully used) in the past.

It's not used in hwloc as far as I know :/
If you're really trying to configure/build hwloc, please use hwloc 1.6
instead (from [1]), and report the problem to hwloc-users as explained
above. Please include your config.log and configure output in the mail.
Thanks!
