Old executables directly pass _init() and _fini() to
__libc_start_main, so they'll work normally.  Of course, the
preinit_array, init_array, and fini_array in such executables won't be
executed either, but since this support is new, those binaries
presumably don't have such sections.  Also, ld.so should take care of
executing init_array and fini_array for the shared objects that the
executable depends on, so I think everything should be fine.
