    heimdal_build: Improve error and warning handling on old and new compilers
    
    The previous commit 1eadeaed0a6ca3a58eb9fd176a7ae5bcc28f64ef had a couple of
    errors, the unpicky flags were being set on all builds (not just old
    compiler builds) due to confusing variable names, and Ubuntu 16.04
    would not build (for fuzzing) because it thought some variables
    were maybe-uninitialized.
    
    This keeps stricter warnings->errors on modern compilers while
    allowing the full build, even in the near future when a modern
    Heimdal is imported.
