-# and the third is the machine configuration.  You may pass in as
-# many groups of configurations as you wish.  Each item passed in is
-# seperated by whitespace.
-#
-# Example:
-#	TARGET_CONFIGS="release ppc default debug i386 default release arm MX31ADS"
-# Parameters may be in upper or lower case (they are converted to upper).
-#
-# "default" parameter is a special case.  It means use the default value for 
-# that parameter.  Here are the default values for each configuration:
-#
-# default kernel configuration = DEFAULT_KERNEL_CONFIG
-# default architecture configuration = system architecture where you are running make.
-# default machine configuration for ppc = none at this time.
-# default machine configuration for i386 = none at this time.
-# default machine configuration for x86_64 = none at this time.
