    libsanitizer, Darwin: Restrict build to Darwin 16 or newer.
    
    The latest import has added dependencies on system resources that are not
    present until Darwin 16.  It might be possible to work around these for
    earlier systems, but in the short-term we have to disable the build so that
    bootstrap completes.
