Usage of $(call cmd,...) is standard way to call other commands which
generate things.
It also has the advantage of printing build information in the form
KWBCFG arch/arm/mach-mvebu/kwbimage.cfg
if verbosity is disabled, and printing the build command otherwise.
Note that the '#' character needs to be escaped in Makefile when used as
value for make variable assignment.
