[POWERPC] print backtrace when entering xmon
xmon does not print a backtrace per default. This is bad on systems with USB keyboard, the most needed info about the crash is lost. print a backtrace during the very first xmon entry. Booting with xmon=nobt disables the autobacktrace functionality. Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Paul Mackerras <paulus@samba.org>
