i was responding to your *general* statement that you wish to get rid of all 
board config.mk's.  and my simple response that this goal is not feasible.  so 
to back up my statement with fact, i gave real world examples that are not 
attainable if you punt all board config.mk's.

ive explained in the past why.  one of the reasons why i think config.mk makes 
more sense is this setting is only used for compilation (build flags).  it 
isnt used directly anywhere in the config.h or related code.  i also find it 
significantly cleaner than the cpu handling as found in the arm or m68k or ppc 
ports where copy & pasting swaths of code is the rule.
