* log.h: Test for SA_SIGINFO to see whether zlog_signal takes final
two args (siginfo and program_counter).
* log.c: (hex_append) Include this function only if SA_SIGINFO or
HAVE_GLIBC_BACKTRACE is defined.
(zlog_signal) Final two args (siginfo and program_counter) now
depend on whether SA_SIGINFO is defined on this platform.
* sigevent.c: (program_counter) Do not include this function if
SA_SIGINFO is not defined on this platform.
(exit_handler,core_handler) Test for SA_SIGINFO to decide whether
2nd & 3rd arguments are present and to decide how to invoke
zlog_signal.
(trap_default_signals) Test for SA_SIGINFO and invoke sigaction
appropriately.
