title: Set GCC version for make in shell
body: <p>I have two gcc (same applies to g++) versions installed. The newer one is the default one:</p>
  
  <pre><code>/usr/bin/gcc      # 4.9.2
  /usr/bin/gcc-4.4  # 4.4.7
  </code></pre>
  
  <p>For my make command I want to use gcc-4.4 / g++-4.4. </p>
  
  <p>I've tried these three variantes but none seems to work:</p>
  
  <pre><code>export CC="gcc-4.4"
  export CPP="g++-4.4"
  
  export CC=/usr/bin/gcc-4.4
  export CPP=/usr/bin/g++-4.4
  
  export gcc=/usr/bin/gcc-4.4
  export g++=/usr/bin/g++-4.4
  </code></pre>
  
  <p>The Makefile defines:</p>
  
  <pre><code># Compiler Options
  CC       = gcc
  CPP      = g++
  LD       = g++
  </code></pre>
  
  <p>The compiler used by the Makefile is still 4.9.2. How can I use 4.4.7?</p>
