debirf fails to build etch image

[jrollins]

In response to ticket #90, I tried to build an etch rescue image, only to have that also fail:

...
I: Extracting tar...
I: Extracting tzdata...
I: Extracting util-linux...
I: Extracting zlib1g...
I: Installing core packages...
W: Failure trying to run: chroot /srv/debirf/rescue/root dpkg --force-depends --install var/cache/apt/archives/base-files_4_i386.deb var/cache/apt/archives/base-passwd_3.5.11_i386.deb

This also appears to be a fakechroot issue, being incompatible with the libc version in the etch chroot.
