[PATCH xserver] sdksyms: Skip empty symbols

[Adam Jackson]

Apparently on NetBSD we can hit failures like this:

sdksyms.c:1773:15: error: expected expression before ',' token
     (void *) &,                                                  /* ../../dri3/dri3.h:110 */

I've been unable to reproduce that locally (even in a NetBSD vm), but
an obvious workaround might be to just notice empty symbol names and
ignore them rather than emit invalid C code.
