Description: Fix compiler check in configure
 Using '-o /dev/null' in the command fails when the compiler uses collect2
 to generate the final link.  Change to using default a.out.

 pngquant (2.3.0-1) unstable; urgency=medium
 .
   * New upstream version
   * configure:  Use a.out for compiler check.
