    Resurrect GDB index generation (RhBug:1410907)
    
    Commit 54d30ac4a344770571e56c60281a9130b61c1788 broke GDB index
    generation due to a leftover "[". In git master this got fixed in
    commit 67d3df338875ad5d9601e360bfdbd4289f271bc1 but we don't want
    that on 4.13.x because there are behavior changes involved, so
    fixing this specifically on the 4.13.x branch.
