I've patched the latest glibc to to provide the symlink.  This is
what I get:
apt-get upgrade
Reading Package Lists... Done
Building Dependency Tree... Done
The following packages will be upgraded:
  libc6 libc6-dev
2 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B/8813kB of archives.
After unpacking 135kB of additional disk space will be used.

(Note that is a patched 2.3.2.ds1-19, didn't change the version
number yet.)

At that point the /lib64 symlink it owned by the libc6 package.

Now I just need to be sure how to package this properly so
nobody has problems updating libc6 and base-files at the
same time.  Any hint welcome.
