In case CONFIG_X86_MCE_THRESHOLD and CONFIG_X86_THERMAL_VECTOR are disabled,
kernel build fails as follows.
arch/x86/built-in.o: In function `trace_threshold_interrupt':
(.entry.text+0x122b): undefined reference to `smp_trace_threshold_interrupt'
arch/x86/built-in.o: In function `trace_thermal_interrupt':
(.entry.text+0x132b): undefined reference to `smp_trace_thermal_interrupt'
In this case, trace_threshold_interrupt/trace_thermal_interrupt are not needed
to define.
So, add config option checking to their definitions in entry_64.S.
