What about .dtors?  You have the same problem there.  I suspect, but
haven't verified, that .ctors.* and .dtors.* also need reversing.  If
that is true then it would be better to do your reversing trick for
anything going to the .init_array output section that isn't named
.init_array* and similarly for .fini_array.

You also need to reverse any dynamic relocations applying to the
sections you are reversing.
