Markus,
I did exactly what you did except for the line:
"`libc-bin.triggers' -> `libc-bin.triggers.old'"

My lines are:
=================================================
$ sudo apt-get  --reinstall install libc-bin
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 1 reinstalled, 0 to remove and 15 not 
upgraded.
1 not fully installed or removed.
After this operation, 0B of additional disk space will be used.
Do you want to continue [Y/n]? y
Setting up libc-bin (2.10.1-0ubuntu16) ...
dpkg (subprocess): unable to execute installed post-installation script: 
Exec format error
dpkg: error processing libc-bin (--configure):
  subprocess installed post-installation script returned error exit status 2
Errors were encountered while processing:
  libc-bin
E: Sub-process /usr/bin/dpkg returned an error code (1)
===========================================================

But I will try your suggestion and use your libc-bin.trigger file. I let 
you know the results.
