elf32-arc.c: Don't cast between function pointer and void pointer
Casts should be avoided if at all possible, and in particular the C
standard doesn't promise that function pointers can be cast to void*
or vice-versa. It is only mentioned under J.5 Common extensions,
saying "The following extensions are widely used in many systems, but
are not portable to all implementations."
* elf32-arc.c (replace_func): Correct return type.
(get_replace_function): Use a replace_func function pointer rather
than void*. Update associated ARC_RELOC_HOWTO define.
