[PATCH V2] perf tools: Fix build on powerpc broken by pt/bts

[Adrian Hunter]

It is theoretically possible to process perf.data files created on
x86 and that contain Intel PT or Intel BTS data, on any other
architecture, which is why it is possible for there to be build
errors on powerpc caused by pt/bts.

The errors were:

	util/intel-pt-decoder/intel-pt-insn-decoder.c: In function âintel_pt_insn_decoderâ:
	util/intel-pt-decoder/intel-pt-insn-decoder.c:138:3: error: switch missing default case [-Werror=switch-default]
	   switch (insn->immediate.nbytes) {
	   ^
	cc1: all warnings being treated as errors

	linux-acme.git/tools/perf/perf-obj/libperf.a(libperf-in.o): In function `intel_pt_synth_branch_sample':
	sources/linux-acme.git/tools/perf/util/intel-pt.c:871: undefined reference to `tsc_to_perf_time'

	sources/linux-acme.git/tools/perf/util/intel-pt.c:915: undefined reference to `tsc_to_perf_time'

Changes in V2:

	Use:
		libperf-$(CONFIG_X86) += tsc.o
		libperf-$(CONFIG_AUXTRACE) += tsc.o

	instead of:

		libperf-$(if $(CONFIG_X86)$(CONFIG_AUXTRACE),y) += tsc.o
