    nscd: cleanup obsolete _FORTIFY_SOURCE setting
    
    This was added in 233399bce2e79e5af3b344782e9943d5f1a9cdcb just for warn_if_unused
    warnings rather than anything substantial.
    
    Now that we have a proper configure argument for F_S (--enable-fortify-source),
    just drop this entirely, to avoid conflicting with e.g. detected --enable-fortify-source
    finding F_S=3, then nscd's Makefile setting F_S=2, resulting in a build-failure
    because of the redefinition.
