		When enabled, each device builds it's own image, including only the
		profile packages for that device.  (Marked as {M}) You will be able
		to change a package to included in all images by marking as {*}, but
		will not be able to disable a profile package completely.
		
		To get the most use of this setting, you must set in a .config stub
		before calling "make defconfig".  Selecting TARGET_MULTI_PROFILE and
		then manually selecting (via menuconfig for instance) this option
		will have pre-defaulted all profile packages to included, making this
