I don't like "powerpc" which usually stands for Power PC 32 bits.

I think the reason the kernel is using "powerpc" is historical and there
are so many architecture managed beyond (ppc32, ppc64, embedded,
system...), that this may be confusing.

AFAIK, when dealing with user space packages, it is a common situation
to have 'ppc64' (and sometimes ppc64le) for PowerPC 64 bits and
'powerpc' for PowerPC 32 bits.

Furthermore this is following the uname -m returned value.
