Log:
 Here is my suggestion for supporting different BSP's in the same buildroot structure. 
 The rest of the BSP depends on fixing the names of the different
 directory structures and cannot be properly submitted until this is fixed.
 ----------------------------
 Add BR2_HOSTNAME which you set to define your build directory
 It is also written to $(TARGET_DIR)/etc/hostname

 Add BINARIES_DIR directory, 
 where resulting binaries can be stored
 Typically this directory contains a subdirectory for each BSP.
 BINARIES_DIR:=$(TOPDIR)/binaries/$(BR2_HOSTNAME)

 Add TARGET_BUILD_DIR directory, where BSP for different
 boards can be built without destroying results of previous builds.
 Typically each BSP would build in a subdirectory of TARGET_BUILD_DIR
 TARGET_BUILD_DIR:=$(TOPDIR)/target_build_<arch>/$(BR2_HOSTNAME)

 Move TARGET_DIR to $(TARGET_BUILD_DIR)/root to allow each board
 to have their own root directory

 Define a "DATE" of build the root file system, 
 which can be used for various filenames.
