miscellaneous one-liner initializations

While not needed for "ordinary" builds on Fedora, these changes are
necesary to build RPMs for Fedora and EPEL.

Where an ordinary build is defined as: clone, cmake, make, ....

Building RPMs for Fedora and EPEL means adding %hardened_build and
using the %cmake macro. These add extra options to the invocation of
cmake and the extra gcc compiler options -Wunintialized -Werror, among
others. Without these fixes the build will fail.
