Please see bug 14752, which tracks a number of issues related to Lustre
building on PPC.  The problem you report above is fixed in bug 14844
already, and there are some others (e.g. bug 14845) that have patches
and others that do not.

Feedback here, or in the bugs themselves, is welcomed as our ability
to test on PPC hardware is very limited.

Cheers, Andreas
