Subject: [PATCH] configure.ac: Do not fatalize -Wmissing-prototypes

There comes below error when run "make -C tests/nsm_client nsm_client"
| nlm_sm_inter_svc.c:20:1: error: no previous prototype for 'nlm_sm_prog_3' [-Werror=missing-prototypes]

It is because rpcgen doesn't generate -Wmissing-prototypes
free code for nlm_sm_inter_svc.c with below logic
in tests/nsm_client/Makefile.am
[snip]
GENFILES_SVC    = nlm_sm_inter_svc.c
[snip]
$(GENFILES_SVC): %_svc.c: %.x $(RPCGEN)
        test -f $@ && rm -rf $@ || true
        $(RPCGEN) -m -o $@ $<

So add the logic not to fatalize -Wmissing-prototypes.
