Makefile: Add CONFIG_BUILD_TARGET to automatically build an special image

Add target to build it automatically upon "make" / MAKEALL. This can/should
be set by board / cpu specific headers if a special U-Boot image is
required for this SoC / board.

E.g. used by Marvell Armada XP to automatically build the u-boot.kwb
target.

CONFIG_BUILD_TARGET
Some SoCs need special image types (e.g. U-Boot binary
with a special header) as build targets. By defining
CONFIG_BUILD_TARGET in the SoC / board header, this
special image will be automatically built upon calling
make / MAKEALL.
CONFIG_IDENT_STRING
If defined, this string will be added to the U-Boot
