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: 1.13.7
