title: Suppress all make output except for errors and warnings
body: <p>I have a makefile which builds a project composed of many files which all need to be built. </p>
  
  <p>To make matters more complicated, I have a number of included directories in each call to gcc (so each call to gcc looks long on the command line). </p>
  
  <p>I'd like to suppress all output except for errors and warnings (so that I can actually see them when make runs!)</p>
  
  <p>Is there any way to do this?</p>
