Some commands such as $(cmd_CC) etc already handle the quiet vs verbose mode in the makefile, but sometimes we may want to pass other info. The new "qinfo" macro can be called with a 9-char string argument (spaces included) as a prefix for some commands, to emit that string when in quiet mode. The caller must fill the spaces needed for alignment. E.g: $(call quinfo, CC )$(CC) ...
