title: Compile GCC and install to DESTDIR
body: <p>I'm trying to install GCC into <code>/my/custom/path/gcc</code></p>
  
  <p>but for some reason it installs into the normal installation path.</p>
  
  <p>the commands i'm using:</p>
  
  <pre><code>configure --target=i686-pc-linux-gnu --disable-nls --enable-languages=c,c++ --without-headers
  make DESTDIR=/my/custom/path/gcc
  make DESTDIR=/my/custom/path/gcc install
  </code></pre>
  
  <p>What am I doing wrong?</p>
