tracing: make the trace clocks available generally

Browse source

Jeremy Fitzhardinge reported this build failure:

 LD	 .tmp_vmlinux1
 arch/x86/kernel/built-in.o: In function `ds_take_timestamp':
 git/linux/arch/x86/kernel/ds.c:1380: undefined reference to `trace_clock_global'
 git/linux/arch/x86/kernel/ds.c:1380: undefined reference to `trace_clock_global'

Which is due to !CONFIG_TRACING && CONFIG_X86_DS=y.

Expose the trace clock code to CONFIG_X86_DS as well.

[ Unfortunately librarizing doesnt work well - ancient architectures
  with no raw_local_irq_save() primitive break the build. ]
