Actually, no. You have to use the library name, so libaoss.so is
valid, /emul/.../libaoss.so is not.
However, the search path in this case is pretty limited. I had to
make a symlink from /usr/lib32/libaoss.so to
/emul/linux/x86/usr/lib/libaoss.so to get aoss to preload as a normal
user.

Well I'm glibc-2.5 on both amd64 and x86, so I can't say for certain
what happens with 2.4, but yes, I believe it was dropped in all sane
versions of glibc. In particular, none of my tests today on amd64 or
x86 revealed any significant problem in actually preloading the
libraries (other than the symlink issue I noted above, and of course,
needing to chmod 4755 the library to be preloaded).
FYI, I also reported the preloading problem via bugzilla way back when:

Unfortunately, even though I can get all the right libraries to load,
I cannot get sound to work reliably on amd64. Neither aoss nor vmdsp
seem to work for me, either as a user or root.
However, I think I know how to make aoss work as a normal user on your
system. You should just need to:
# chmod 4755 /emul/linux/x86/usr/lib/libaoss.so.0.0.0
# ln -s /emul/linux/x86/usr/lib/libaoss.so /usr/lib32/libaoss.so
The first command is just to make sure the library is setuid.
For vmdsp, my best guess is that a 64-bit artsd won't communicate with
32-bit clients. But that is just a guess.
FYI, on my x86 laptop both vmdsp and aoss work, although aoss produces
choppy audio.
HTH,
