    lang/smalltalk: use modern memory management
    
    The memory allocator defaults to some horrifying complex code to manage
    mmap'd allocations.  On system where MAP_NORESERVE is defined (Linux) it
    uses a much simpler approach relying on memory overcommit.  Enable this
    code on FreeBSD by defining MAP_NORESERVE to 0 (all allocations
    are MAP_NORESERVE on FreeBSD unless a sysctl is set).
    
    Entierly disable the other code path as it (somewhat gratutiously) uses
    sbrk.
