    Fix build with -O3 on ppc64el
    
    Ubuntu runs ppc64el builds with -O3, which elicited a few warnings
    from gcc that were not generated elsewhere, as documented at
    https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/1592841 .
    
    Initialize the output variable at the top of a couple of helper functions
    to silence the uninitialized-variable warnings.
    
    (cherry picked from commit 7db89952d8d4f806ac8b4908f898ac651df11643)
    
    ticket: 8475
    version_fixed: 1.14.4
