The typical biarch setup is to have 2 versions of most libs, but pretty
much everything running 32 bits by default, only specific apps that take
benefit of beeing 64 bits beeing built 64 bits...

It would be useful to use gentoo to do a more complete performance and
size comparison though, since they have both fully 32 and fully 64 bits
ppc environments.
