Remove /usr/i486-linux-libc6 from /etc/ld.so.conf and run ldconfig again.

You might want to remove the whole i486-linux-libc6 directory.

The problem you have is documented in the glibc FAQ 3.18:
3.18.	After upgrading to glibc 2.1, I receive errors about
        unresolved symbols, like `_dl_initial_searchlist' and can not
        execute any binaries.  What went wrong?

{AJ} This normally happens if your libc and ld (dynamic linker) are from
different releases of glibc.  For example, the dynamic linker
/lib/ld-linux.so.2 comes from glibc 2.0.x, but the version of libc.so.6 is
from glibc 2.1.

The path /lib/ld-linux.so.2 is hardcoded in every glibc2 binary but
libc.so.6 is searched via /etc/ld.so.cache and in some special directories
like /lib and /usr/lib.  If you run configure with another prefix than /usr
and put this prefix before /lib in /etc/ld.so.conf, your system will break.
[...]

You can even call the dynamic linker by hand if everything fails.  You've
got to set LD_LIBRARY_PATH so that the corresponding libc is found and also
need to provide an absolute path to your binary:

        LD_LIBRARY_PATH=<path-where-libc.so.6-lives> \
        <path-where-corresponding-dynamic-linker-lives>/ld-linux.so.2 \
        <path-to-binary>/binary

For example `LD_LIBRARY_PATH=/libold /libold/ld-linux.so.2 /bin/mv ...'
might be useful in fixing a broken system (if /libold contains dynamic
linker and corresponding libc).
