Do you really need to do this?

rs6000-tdep.c already has the following in it:

  if (sysv_abi)
    set_gdbarch_long_double_bit (gdbarch, 16 * TARGET_CHAR_BIT);
  else
    set_gdbarch_long_double_bit (gdbarch, 8 * TARGET_CHAR_BIT);

So, if I'm not mistaken, the size of long doubles should already be
set correctly.
