I agree - it is not really a different BSP; rather a configuration issue

I agree with having it as a configuration option. I am quite happy to 
use a different config option set for the PC104 and DIMMPC. In my case, 
I am using different BSPs for the boards--pc386dx for DIMMPC and pc586 
for PC104.  If someone was using the same BSP, they could change the 
--prefix in the config to a different path for each different 
configuration. It just means that I have to change my 
RTEMS_MAKEFILE_PATH variable during the build (which I have to do 
anyway) to point to the different directory
