Minor nit: "Building OpenJDK .."

[David Holmes]

common/makefiles/MakefileHelpers.gmk always reports that it is building 
OpenJDK even if it is not:

define PrintStartMessage
     $(if $(VERBOSE),,@$(ECHO) Running make as $(MAKE) $(MFLAGS) 
$(MAKE_ARGS))
     $(call CheckEnvironment)
     @$(ECHO) "Building OpenJDK for target $(if 
$(MAKECMDGOALS),'$(MAKECMDGOALS)','all') in configuration '$(CONF_NAME)'"
endef

define PrintEndMessage
     @$(ECHO) "Finished building OpenJDK for target '$@'"
     $(call CheckEnvironment)
endef
