ld fails to link if library order is reversed

[Nilmoni Deb]

Lets say I am running the following command

        gcc z.o -lX -lY -o z

and libX.a depends on a function that is defined in libY.a then the order
of linking appears to be important. While the previous command works, the
next one (with order reversed) will fail:

        gcc z.o -lY -lX -o z

This problem has been observed with binutils version 2.10.91. I would
think that ld should look back when resolving dependencies.
