This bug was fixed in the package eglibc - 2.13-8ubuntu3

---------------
eglibc (2.13-8ubuntu3) oneiric; urgency=low

  * debhelper.in/libc.preinst: Don't probe for old copies of libc when doing
    initial installs (i.e. no second argument to preinst), since debootstrap
    extracts libc and other packages before unpacking it properly and we
    don't want to break it (LP: #805342).
