I noticed that the function decls for builtin functions were all being
marked as varargs. This perplexing problem turned out to be due to
void_list_node not being initialized when the builtin functions were
declared. Why the frontend needs to initialize void_list_node is beyond
me, but I'm not going to change that today. This patch fixes the
problem. Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
Committed to mainline.
