Fix ldscripts such that ld(1) collects the .fini_array section in the same

order as the .init_array section.  Finalisation routines need to be called
in the opposite order as their corresponding initialisation routines but
rtld(1) handles that by calling the function pointers in .fini_array in
reverse order.
