That's an error you should see when trying to run the downloaded bash
binary without doing a chroot first (the wheezy libc doesn't define
GLIBC_2.15), eg, (di2 is a debootrapped i386 Devuan jessie on a amd64
host),

[rw@doppelsaurus]~#cd /tmp/di2
[rw@doppelsaurus]/tmp/di2#bin/bash
bin/bash: /lib/i386-linux-gnu/i686/cmov/libc.so.6: version `GLIBC_2.15' not found (required by bin/bash)

The library name also comes from the Wheezy system, it should be

/lib/i386-linux-gnu/libc.so.6

for the one which was downloaded.

You could try to have a look at the downloaded library. Assuming you're
root and the cwd is the top-level download directory (/mnt/debinst in
your case) then

nm -D `find -name libc.so.6` | grep GLIBC

should print
