OK. I see. I was under the impression (and am pretty sure now after
checking back) that .../usr/bin/arm-linux-gnueabi-gcc (or in the hf-case
.../usr/bin/arm-linux-gnueabihf-gcc-4.7) is only available in the chroot
after *running* finish_chroot_install.sh.
So the existence of .../usr/bin/arm-linux-gnueabi... does not indicate
that finish_chroot_install.sh is missing but that it wasn't run yet.
That's why I think you should use
[ ! -e ../qtmoko-chroot/finish_chroot_install.sh ]
in that particular if-clause.

My real problem was that cdebootstrap threw an error (due to the
previously mentioned bug in my version of it). So the "until ... do"
loop in line 37 was endless and I had to cancel the script which in turn
lead to the bind-mounts not being done.
Now after fixing the script (using debootstrap) and rerunning it I
indeed see the mounts!

Thanks.
