Subject: 	BSP Patch: 
 ========================================================= 	The purpose of
 the BSP patch is to allow building 	several boards inside the same
 buildroot tree. 	For this to work, each board has to have its 	own
 "$(TARGET_DIR)" and all *configurable* packages 	must be rebuilt for
 each board. 	They are now built in the "$(PROJECT_BUILD_DIR)" 	All
 non configurable packages can and should still 	be built in the
 "$(BUILD_DIR)". 	If a package is built for one board, then when 	you
 build for a second board of the same architecture 	the build becomes a
 simple copy of the resulting 	binaries.

	-----
	Define BR2_PROJECT which will be used as the selector
	between different boards. Note that BR2_PROJECT allow
	you to build multiple root file systems for a single 
	board, and should not be confused with BR2_BOARD_NAME
	which relates to the H/W.

	-----
	Define PROJECT_BUILD_DIR as 	"PROJECT_BUILD_DIR/$(PROJECT)"
	Define BINARIES_DIR as 		"binaries/$(PROJECT)"
	Define TARGET_DIR as		"$(PROJECT_BUILD_DIR)/root"
	(some prefix/postfix may apply)

	Resulting images are stored in	"$(BINARIES_DIR)"

	-----
	Define a few new environment variables in Makefile

	PROJECT:	Stripped BR2_PROJECT
	DATE:		Date of build in YYYY-MM-DD format
	HOSTNAME:	Stripped BR2_HOSTNAME	=> /etc/hostname
	BANNER:		Stripped BR2_BANNER	=> /etc/issue

	Linux and Busybox will be built in $(PROJECT_BUILD_DIR)
	More patches will be needed later to ensure all
	configurable packages are built in this directory.
