Well, here's the most recent description of that non-trivial way:
http://sourceware.org/ml/binutils/2011-02/msg00099.html

This is the patch I've used for readline already using some helper scripts:
http://prefix.gentooexperimental.org/hg/prefix-tree/file/db3e43bd681a/sys-libs/readline/files/readline-6.2-aixso.patch

And here's the wrapper scripts, installed as CHOST-mkexpfile, and ld used by 
$CC:
http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-devel/native-cctools/files/aix-2/

The problem with these scripts right now is the additional external dependency
during bootstrap, which I can drop with a package-private libtool script, as in:
http://prefix.gentooexperimental.org/hg/prefix-tree/file/db3e43bd681a/sys-libs/readline/readline-6.2_p1-r1.ebuild#l82

Still I doubt you really want to integrate these scripts into readline...

Thanks!
