The root-cause of this is the manually modeled dependency chain in
sbuild-chroot.inc around libgcc-<...> and libstd++-<...>. The
assumptions made there are not universally valid, especially not when
packages are taken from debian security (which explains the late
breakage). This was introduced by Jan to reduce the sbuild install
times in 2be866677 and d90f75bd00f. Reverting the changes fixes the
build.

Still I don't fully understand why this breaks non-deterministically.
