The ss555 BSP uses -mcpu=505, because as far as I can tell, it's the most
appropriate gcc cpu variant for the MPC555.  From what I can see in the
source for gcc (up to 3.4.1), there is no other -mcpu=5xx variant available.

If a 555 variant has been added in newer versions of gcc, I'd like a chance
to test it before the m505 multilib disappears.
