sys_siglist (like Solaris 2.7.)
* acconfig.h (NEED_DECLARATION_STRSIGNAL): Provide a stub.
* collect2.c: Don't declare `sys_siglist' here.
(my_strsignal): Prototype and define new function. Use it in
place of `sys_siglist' hacks.
* mips_tfile.c: Likewise.
* configure.in (AC_CHECK_FUNCS): Check for strsignal.
(GCC_NEED_DECLARATIONS): Likewise.
* system.h (strsignal): Prototype it, if necessary.
(sys_siglist): Declare it, if necessary.
