    build: Don't automatically use _FORTIFY_SOURCE
    
    OS builders can add this flag externally if desired.  The problem with
    us doing this unconditionally, it causes the cpp to spam us with
    warnings if we're building without optimization (i.e. CFLAGS='-ggdb
    -O0') which I often do so I can use gdb.
