Kbuild: allow building tools without board configuration
Prior to Kbuild, U-Boot could build under tools/ directory
withour configuring for a specific board.
That feature was lost when switching to Kbuild.
This patch revives it again by adding a make target "tools-only".
Usage:
$ make tools-only
Neither board configuration nor cross compiler are required to
build host tools.
