binutils-2.22: ld and --copy-dt-needed-entries

Just for your information.
It seems that ld from binutils-2.22 by default has --no-copy-dt-needed-entries
behavior, and so explicit --copy-dt-needed-entries is now needed where the
previous default behavior is relied upon.

A short excerpt from the man page for your convenience:

> This option also has an effect on the resolution of symbols in
> dynamic libraries.  With --copy-dt-needed-entries dynamic libraries
> mentioned on the command line will be recursively searched,
> following their DT_NEEDED tags to other libraries, in order to
> resolve symbols required by the output binary.  With the default
> setting however the searching of dynamic libraries that follow it
> will stop with the dynamic library itself.  No DT_NEEDED links will
> be traversed to resolve symbols.
