You can remove the --with-cpu; the default on AIX4.3 is 604e,
which should work fine. I don't think you can yet remove the
--disable-powercpu since I didn't touch the multilib code (I
completely missed it, and wow it's a nice little maze all of
itself). I have no idea about --disable-aix64. Try and see :-)
