Report a warning when unaccelerated Whirlpool is being used

The warning serves two purposes: it informs the user that they should
expect very slow hashing (i.e. Portage did not hang) and that they
should inform the repository owner about the problem. Far from ideal
but probably good enough given how rare Whirlpool-only ebuilds are.
