Revert rev 1.3. While that change appears to make the behaviour similar to

binutils 2.15, it introduces bogus failures when inter-library dependencies
are present.

With the binutils 2.17 behaviour restored, --as-needed will cause linker
failures when necessary inter-library dependencies are not present.  This is
actually a good thing as binutils 2.15 will silently produce executables
that will fail at runtime in those cases.
