commit 3bad0a21b4d13d8d10691f382c836897fa7a7cb9

    Drop ppc64-specific workaround for versioned symbols
    
    Currently aserver fails to build when using parameter
    --without-versioned, due to an workaround for ppc64
    (06221f86d207cb33ddd4867ca5301eeb247c4400).  This workaround is
    not required anymore on the ppc64 ABI v2, and, in fact is breaking the
    compilation. Reverting this commit
