Historically they have been the most important 32-bit platforms, along
with PReP.

The problem with making all platforms default to N is that if you take
the default values for all config options you end up with a config
that won't build.  So we want at least one platform to default to Y,
and pmac has been as good a choice as any for that (and probably still
is).
