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
‘intel_pt_insn_decoder’:
util/intel-pt-decoder/intel-pt-insn-decoder.c:138:3: error: switch
