The problem does appear to be ppc64 vs ppc related.  On a PS3 machine
with a ppc64 kernel and ppc userspace, the stap executable is built as
a 32-bit program but staprun (see bug#4037) is 64-bit.  Bundled
elfutils would have to be built for both -m32 and -m64.

I'd rather see bug #4037 fixed.  Plus, I'd prefer staprun/stapio not
have to engage in ELF processing anyway and leave it to
translation-time (stap).
