 * For highest performance the L1 NH and L2 polynomial hashes should be

 * for the rest (32-bit) architectures.
 * For each, nh_16 *must* be defined (works on multiples of 16 bytes).
 * Optionally, nh_vmac_nhbytes can be defined (for multiples of
 * VMAC_NHBYTES), and nh_16_2 and nh_vmac_nhbytes_2 (versions that do two
