  Log:
  Fix backward compatibility of the "old" (i.e. FreeBSD6) lseek
  syscall. It was broken when a new lseek syscall was introduced.
  The problem is that we need to swap the 32-bit td_retval values
  for the __syscall indirect syscall when the actual syscall has
  a 32-bit return value. Hence, we need to exclude lseek(2). And
  this means the "old" lseek(2) as well -- which we didn't.
