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
all targets.

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. :)
