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
ranlib: supported targets: elf64-x86-64 elf32-i386 elf32-x86-64
a.out-i386-linux pei-i386 pei-x86-64 elf64-l1om elf64-k1om elf64-little
elf64-big elf32-little elf32-big pe-x86-64 pe-bigobj-x86-64 pe-i386
