title: AVR32/GCC Linker warning: input is not relaxable
body: <p>I am trying to compile an AVR32 program with GCC 3.4.2 and getting the following linker warning:</p>
  
  <p><code>input is not relaxable</code></p>
  
  <p>Could someone explain what that warning means?</p>
  
  <p><em>Linker flags</em>: <code>-Wl,--start-group  -Wl,--end-group -Wl,--gc-sections -mpart=uc3c0512c -Wl,--relax -Wl,-e,_trampoline</code></p>
