BUILD: makefile: add a qinfo macro to pass info in quiet mode

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) ...
