I would prefer to avoid an explosion of build cases. The addition of bare
BSP cases is going to have a serious impact on how long it takes to build
There are two questions to consider on each case:
+ Does RTEMS differentiate between two CPU models?
+ Do the tools (gcc, binutils, newlib) distinguish between the tools?
So bare-m68302 is not needed from a tools perspective. The remaining
question is whether it is necessary from an RTEMS perspective.

Thanks. The computer caught that stupid one. :)
