I thought that could be the problem. But that isn't it, or not just
that (see spooky part below).
I 've put the mangled Packages file at
http://mrvn.homeip.net/ftp.de.debian.org_debian_dists_sid_main_binary-armel_Packages.bz2
if you want to try yourself.

Where does that come from suddenly? Testing some more I find that adding
libdb1-compat-armel-cross to the Packages file makes libc6-armel-cross
disapear:

Description: The Berkeley database routines [glibc 2.0/2.1 compatibility]
libdb is a library for manipulating database files, developed at Berkeley.
.
It supports three kinds of file formats:
* btree. A representation of a sorted, balanced tree structure.
* hashed. An extensible, dynamic hashing scheme.
* UNIX file oriented. A byte stream file with fixed or variable length
records.
.
This library exists for compatibility with applications built against
glibc 2.0 or 2.1. There is intentionally no corresponding development
package. Do not link new applications against this library!

======================================================================
Testing some more I find that the problem is the Replaces line. Changing
libc6-armel-cross to Changing libc6-armel-cross2 makes libc6-armel-cross
appear. Changing it back makes it disapear.
