Hi,
binutils-gold will be the default for next Debian and Ubuntu release.
The main difference is that --no-add-needed is the default behavior of GNU
binutils-gold. This means that you need to provide all needed libraries to the
linker when building your executables.

Here is the interesting part of the log file:
