Hi,

If you compile tip.git on ARM32 (or ARM64, I bet) you compile link time errors:

libperf.a(libperf-in.o): In function `intel_pt_synth_branch_sample':
/home/ubuntu/perfmon/linux/tools/perf/util/intel-pt.c:899: undefined
reference to `tsc_to_perf_time'
libperf.a(libperf-in.o): In function `intel_pt_synth_transaction_sample':

That's because if AUXTRACE is detected, it pulls in x86 specific stuff
like intel-pt. This should
be decoupled.
