title: Huge size of /lib/modules/3.19.3 while building custom kernel
body: <p>I was building Linux 3.19.3 for my Linux Mint 64-bit laptop, and ran out of space because of a huge <code>/lib/modules/3.19.3</code> folder.</p>
  
  <p>I used the config file for 3.16.0-31-generic that was supplied by my Mint updates, reverting to default for any new parameters.</p>
  
  <p>Size of <code>/lib/modules</code> for various kernels:</p>
  
  <pre><code>184M    /lib/modules/3.13.0-24-generic
  193M    /lib/modules/3.15.0-031500-generic
  191M    /lib/modules/3.16.0-29-generic
  192M    /lib/modules/3.16.0-31-generic
  4.0K    /lib/modules/3.16.1-031601-generic
  2.3G    /lib/modules/3.19.3
  608K    /lib/modules/3.8.0-31-generic
  </code></pre>
  
  <p>And this size is despite <code>make modules_install</code> being interrupted due to lack of disk space.</p>
  
  <p>Even some of the older kernels listed here were custom compiled. Is there any parameter I'm missing?</p>
