Right. People have started muttering about 1.5, and I think we need to
start working on this now.

I like the idea of having the aout libraries in a subdirectory. So for
instance if ld.so (or ld.aout_so) finds /foo/bar/libZ.so.*.* is an elf
lib, it looks at /foo/bar/aout/libZ.*.
I'm not sure if, given an -R/path, it should look at /path/aout first, or
if it should look at /path and roll over to /path/aout as above. I'd
suspect -R/path/aout, then /path if /path/aout doesn't exist.
I'm not sure what to do about finding a.out libs in /path if /path/aout
As for two ld's, don't we have two now?
Also, what about upgrading packages??
