    tests: Fix 'type defaults' error in link_cond due to main not being 
properly declared
    
    This is related to an effort to prepare Automake for future GCC/Clang
    versions which set c99 as default standard to be used.
    Not properly declaring main as "int main(...)" is rejected since c99.
    
    * t/link_cond.sh: Add (void) to main definition.
