xm-svr4.h (SYS_SIGLIST_DECLARED): Define.

        * xm-svr4.h (SYS_SIGLIST_DECLARED): Define.
        * xm-news.h (SYS_SIGLIST_DECLARED): Likewise.
        * gcc.texi: Note that if you define sys_siglist that you should
        also define SYS_SIGLIST_DECLARED.
autoconf doesn't handle finding sys_siglist under different names.
