We thought there was a silent data corruption issue on POWER 7/BE systems, so we blocked building on POWER 7/BE systems altogether. We later figured out that it was just data hangs -- not silent data corruption. So in hindsight, the configure block probably wasn't necessary -- but we didn't know it at the time. Regardless, the hangs have now been fixed, and we're removing the POWER 7/BE block in configure. For more detail on the entire saga, see open-mpi#4349 (comment). Signed-off-by: Jeff Squyres <[email protected]> (cherry picked from commit 3f0ccff)
Also note that ARM and POWER users may experience hangs (until open-mpi#4563 is fixed). Signed-off-by: Jeff Squyres <[email protected]>

Per #5034 and larger discussion on #4349.
Still waiting for #4563 to be fixed (to resolve hangs on some ARM/POWER platforms), but that's a different issue.
RM: Note that the NEWS commit here is specifically for 3.1.1. If you want to pull this back to v3.1.0, I can adjust the NEWS commit.
