__malloc_hook, __realloc_hook, __memalign_hook,
__after_morecore_hook): Variable definitions moved to ...
* malloc/malloc.c: ... here, so as to be before all references.
* sysdeps/i386/dl-machine.h (elf_machine_load_address): Add a dummy
global variable reference in an unused asm parameter, to ensure the
compiler has set up the GOT register before we use it.
