Cross compiling perf to other platform failed due to missing symbol:

  ...

  LD       /pathofperf/perf-in.o

/pathofperf/libperf.a(libperf-in.o): In function `intel_pt_synth_branch_sample':
/usr/src/kernel/tools/perf/util/intel-pt.c:899: undefined reference to `tsc_to_perf_time'
/pathofperf/libperf.a(libperf-in.o): In function `intel_pt_synth_transaction_sample':
/usr/src/kernel/tools/perf/util/intel-pt.c:992: undefined reference to `tsc_to_perf_time'

/usr/src/kernel/tools/perf/util/intel-pt.c:943: undefined reference to `tsc_to_perf_time'
  ...

This is because we allow newly introduced intel-pt-decoder to be
compiled to not only X86, but tsc.c which required by it is compiled
for x86 only.

This patch fix the compiling error by allow tsc.c to be compiled if
CONFIG_AUXTRACE is set, no matter the target platform.
