I was really only following the instructions on the Linaro Wiki...

...but I imagine various changes between distribution versions makes it
difficult to expect the recipe to work on Squeeze. In any case, this was just
an attempt to keep things simple by not mixing packages from different
distribution versions: toolchain packages, dependencies and source packages
all coming from Squeeze.

I logged into the pdebuild-cross chroot as follows:
pbuilder --login --save-after-login \
--configfile /etc/pdebuild-cross/pdebuild-cross.rc
Then I did the following:
cat > /etc/apt/sources.list.d/backports.list
deb http://ftp.de.debian.org/debian-backports squeeze-backports main
apt-get update
apt-get install xapt
rm /etc/apt/sources.list.d/backports.list
apt-get update
When attempting a pdebuild-cross, I still get the error about apt-cross, so I
don't think I understood the role of xapt here. Nevertheless, this was just an
exercise in choosing a simple configuration, but I think I'm likely to
encounter problems with a somewhat obsolete set of tools.

Is it possible to use Squeeze toolchains with Wheezy? The errors mentioned in
the above quote were encountered with Squeeze toolchains in combination with
Wheezy dependencies and source packages. This kind of combination seems to be
used in the various files found in /usr/share/multistrap, so I thought it
might work.
In this configuration, xapt is installed by pdebuild-cross, but as I mentioned
before, the foreign architecture apt-get operation fails to find packages like
libc6-dev and various build dependencies, and the actual package building
fails in dpkg-checkbuilddeps.

I understand this. I was just wondering whether pdebuild-cross was a viable
option at the moment.
