  Suppress a compiler warning (undeclared function)

This is benign since int abs(int) matches implicit definition.
But the less time we spend analyzing things like this, the better:
../../platforms/Cross/plugins/JPEGReadWriter2Plugin/sqJPEGReadWriter2Plugin.c:70:31: warning: implicitly declaring library funct
ion 'abs' with type 'int (int)' [-Wimplicit-function-declaration]
          pcinfo->input_components = (abs(nativeDepth) != 8 ? 3 : 1);
                                      ^
