One note regarding my report below: I have noticed that autoconf has chosen to use "$srcdir/config/compile xlc" instead of just "xlc" (I set CC=xlc). I strongly suspect this is related, and am investigating why the compile wrapper is used. However, independent of that there does seem to be some flaw in how the atomics are getting built on this configuration.
