Log:
  rm stale ptrace dependencies after r305012
  
  This is similar to r318912, except that ptrace.[sS] was previously a
  file in the source tree, not a generated assembly wrapper.
  
  Check for the existence of ptrace.[sS] in the .depend file to determine
  if we have to clean it up.  This is a bit hackish and will not be left
  in place indefinitely, but provides a useful example case when
  investigating a better solution in bmake.
