-	  This is the processor type of your CPU. This information is used for
-	  optimizing purposes.  To build a library that will run on all ARMCPU
-	  types (albeit not optimally fast), you can specify "Generic Arm" here.
-	  If you pick anything other than "Generic Arm", there is no guarantee 
-	  that uClibc will even run on anything other than the selected
-	  processor type.
-
-	  Here are the settings recommended for greatest speed:
-	  - "Generic Arm" select this if your compiler is already setup to
-	    optimize things properly, or if you want to run on pretty much
-	    everything, or you just don't much care.
-	  - For anything else, pick the ARM core type that best matches the
-	    cpu you will be using on your device.
-
-	  If you don't know what to do, choose "Generic Arm".
