[CLASSES]: Handle DW_TAG_unspecified_parameters in function pointers 

My favourite guinea pig (linux's vmlinux) has not one pointer to a function
that has unspecified parameters (...), but a new guinea pig, also a kernel,
has, openbsd's kernel, example:

/* /usr/home/leonardo/openbsd/src/sys/sys/protosw.h:63 */
struct protosw {
        short int pr_type;              /*     0     2 */
<SNIP>
        void      (*pr_input)(struct mbuf *, ...); /*    12     4 */
        int       (*pr_output)(struct mbuf *, ...); /*    16     4 */
<SNIP>

So fix it!
