title: Resume make compilation process
body: <p>I was compiling Qt5 for a embedded device on the device itself. This takes a long time since Qt sources are about 800mb and the embedded device isn't exactly fast.</p>
  
  <p>Everything was running well, until a power shortage prevented the device from finishing <code>make</code>, therefore halting the compilation process.</p>
  
  <p>Is there any way to resume from where it was left of?</p>
