kbuild: add "cross_tools" target to build tools for the target
Programs in tools/ directory are usually built for the host.
But some of them (mkimage, dumpimge, gen_eth_addr, etc.) are
useful on the target OS too.
Actually, prior to Kbuild, U-Boot could build tools for
the target like follows:
$ make <target_board>_config
$ export CROSS_COMPILE=<cross_gcc_prefix>
$ make HOSTCC=${CROSS_COMPILE}gcc HOSTSTRIP=${CROSS_COMPILE}strip tools
In Kbuild, we can no longer replace HOSTCC at the command line.
In order to get back that feature, this commit adds "cross-tools" target.
Usage:
Build tools for the host
$ make CROSS_COMPILE=<cross_gcc_prefix> tools
Build tools for the target
$ make CROSS_COMPILE=<cross_gcc_prefix> cross_tools
Besides, "make cross_tools" strip tools programs because we
generally expect smaller storages on embedded systems.
