754187ad73 perf build: Remove NO_AUXTRACE build option 
The NO_AUXTRACE build option was used when the __get_cpuid feature
test failed or if it was provided on the command line. The option no
longer avoids a dependency on a library and so having the option is
just adding complexity to the code base. Remove the option
CONFIG_AUXTRACE from Build files and HAVE_AUXTRACE_SUPPORT by assuming
it is always defined.

e467705a9f perf util: Make util its own library 
Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
  arch/common.c
  scripts/perl/Perf-Trace-Util/Context.c
  scripts/python/Perf-Trace-Util/Context.c
are made part of this library.

a54ca19498 perf arm-spe: Support synthetic events 
After the commit ffd3d18c20 ("perf tools: Add ARM Statistical
Profiling Extensions (SPE) support") has been merged, it supports to
output raw data with option "--dump-raw-trace".  However, it misses for
support synthetic events so cannot output any statistical info.

This patch is to improve the "perf report" support for ARM SPE for four
types synthetic events:

  First level cache synthetic events, including L1 data cache accessing
  and missing events;
  Last level cache synthetic events, including last level cache
  accessing and missing events;
  TLB synthetic events, including TLB accessing and missing events;
  Remote access events, which is used to account load/store operations
  caused to another socket.

Example usage:

  $ perf record -c 1024 -e arm_spe_0/branch_filter=1,ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ dd if=/dev/zero of=/dev/null count=10000
  $ perf report --stdio
