x86: fix VisualWS and Voyager kexec build failures
without this patch:
VOYAGER:
kernel/built-in.o: In function `crash_kexec':
(.text+0x28588): undefined reference to `machine_crash_shutdown'
VISWS:
kernel/built-in.o: In function `crash_kexec':
/next-20080401/kernel/kexec.c:1074: undefined reference to `machine_crash_shutdown'
make[1]: *** [.tmp_vmlinux1] Error 1
because arch/x86/kernel/reboot.c isn't built since CONFIG_X86_BIOS_REBOOT=n,
so machine_crash_shutdown() isn't available.
This patch does seem a small bit odd since the KEXEC help text says that
kexec is independent of the system firmware.
