I believe I hit the same bug on amd64. After upgrading, all commands fail with "error while loading shared libraries: /lib/x86_64-linux-gnu/libc.so.6: unexpected PLT reloc type 0x25". /lib/ld-linux-x86-64.so.2 is pointing to a rather old ld-lsb-x86-64.so.3, changing it to point to x86_64-linux-gnu/ld-2.13.so fixes the problem.
