[PATCH 2/2] perf tools: Make NO_AUXTRACE default for non-x86 architectures

[Adrian Hunter <adrian.hunter@intel.com>]

Currently the AUXTRACE infrastructure is only used by Intel PT
and Intel BTS but is compiled into all architectures to support
the ability to process a perf.data file (including one containing
Intel PT or Intel BTS data) from any architecture on any other
architecture.

Generally people don't want that ability with respect to AUXTRACE
by default.

Make the build option NO_AUXTRACE the default for non-x86
architectures.  To build with AUXTRACE on those architectures
use NO_AUXTRACE=0.

The build-test is updated accordingly.
