The i386 vs. x86_64 is well set for 64 bits. Looks like ppc64 brings some
additional issues.

The stuff built on YDL will work also with non-PS3 ppc64. I'd expect the only
really special part could be systemimager.
Seing the ratio of 32bit vs. 64 bit packages on YDL, I would consider very
carefully which packages should be built for ppc64. Most of the libs are missing
for ppc64, so I think the default should be 32 bits. Only for really performance
relevant stuff like MPI libs it is worth building for 64 bits.
Unfortunately building with --target ppc is not straight forward, I saw
%{_lib} = /lib64, and -m32 compiler options, i.e. the rpm macros are not
really helpful here...
Regards,
Erich
