I can't understand that. If we use the 64bit elfspe to run an SPU program, it
will be executed in 64bit mode.

I thought that the ppc64 repository consisted of only the ppc64 packages for 64
bit only userland, while the ppc repository contained 32bit packages for default
runtime environment and additional ppc64 packages for 64bit user programs. Is it
my misunderstanding? Don't we need to consider the 64bit only environment?
