Hi Bernd,

The autobuilder is a Debian Jessie chroot, I can't test it on the system
right now, but testing it on my Jessie laptop shows that ranlib does
support -D in debian:

nroach44 at poseidon:~$ which ranlib
/usr/bin/ranlib
nroach44 at poseidon:~$ ranlib --help
Usage: ranlib [options] archive
 Generate an index to speed access to archives
 The options are:
  @<file>                      Read options from <file>
  --plugin <name>              Load the specified plugin
  -D                           Use zero for symbol map timestamp
  -U                           Use actual symbol map timestamp (default)
  -t                           Update the archive's symbol map timestamp
  -h --help                    Print this help message
  -v --version                 Print version information
