Subject: [PATCH 1/2] tools/perf: set no_auxtrace for powerpc

x86/perf_regs.h is included by util/intel-pt.c, which will get compiled
when buiding perf on powerpc. Since x86/perf_regs.h has
`PERF_EXTENDED_REG_MASK` defined, defining `PERF_EXTENDED_REG_MASK` for
powerpc to add support for perf extended regs will result in perf build
error on powerpc.

Currently powerpc architecture is not having support for auxtrace. So as
a workaround for this issue, set NO_AUXTRACE for powerpc.
