The only reason I ever call "make V=1" myself, (other than when debugging the compiler command-line for some reason), is to ensure whether my CFLAGS, (like "-g -O0" or "-O2"), are actually making it to the command-line. But these are hard to find in the V=1 output, and really, we should just print these even in the quiet case. So do that.
