OK, I now have 2.4.20 on this machine, and although AT_PLATFORM is set
to "i586", it still reports loading the basic versions of the libraries:

I have rerun ldconfig, although I don't know if this is important.
"ldconfig -v -v" definitely shows the i586 libraries being processed
(with hwcap 0x40...)
