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.
