+As you can see, we're manually disabling scalers because we prefer dispmanx for that, which 
+makes scalers unnecessary on a CPU limited platform like this, timestamps because most people
+doesn't have an RTC on the Raspberry Pi, and event recorder to save SD card write cycles.
+All these are automatically disabled when we crosscompile by passing "--host=raspberrypi",
+which is not the case.

 ¡¡It will be an SLOW process, taking several hours to complete, unless you
 are running distcc against a fast compilation server!!
