Board Support Package for Excimer Board

I'm currently working on changing my Excimer BSP from the "old" exception 
model to the "new" exception model.

My previous attempt at a BSP for the Excimer booted but ran into low-memory 
problems since there is only 1MB of RAM on the Excimer and the combination 
of MDINK 32and DINK32 ate most of that.  (For those unfamiliar with the 
Excimer it has 1MB of RAM and 4MB of Flash, a NS16552 DUART, and a 
PPC603e.  Mine has been modified to use a MPC745B processor)

While working on the low-memory problem it was suggested that I change my 
BSP to be based on "a PowerPC BSP with an irq subdirectory or CPU model 
name as mpcXXX".

I'm currently failing to compile due to mpc8xx_set_exception() being an 
undefined reference.  It seems like it should be undefined since I don't 
have a mpc8xx CPU.  I'm trying to figure out what that code does and what 
my code should do instead.

   My code is based on the rtems-ss-20021007 snapshot
