I guess in that case powerpc falls into the same category
as ia64, i.e. it makes up a value to keep ACT_HZ from being
harmful, rather than using ACT_HZ for something helpful.

We should consequently drop the powerpc definition along
with the other bogus ones. This will also help the theoretical
CONFIG_HZ=300 case.
