  tools build: Add feature detection for g++ (2016-10-05 19:59:35 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

- Intel PT timestamp fixes (Adrian Hunter)

- Fix Intel JSON fixed counter conversions (Andi Kleen)

- Sync memcpy, cpufeatures and bpf headers with the kernel (Arnaldo Carvalho de Melo)

- Add some more tool tips (Donghyun Kim, Kim SeonYoung, Nambong Ha)

- Fix libtraceevent's kbuffer_read_at_offset() handling of offsets before or
  equal the first event (Namhyung Kim)

- Fix uretprobe probe placement on ppc64le (Ravi Bangoria)

- Support building C++ source files and add feature detection for g++,
  prep work for supporting a builtin clang/llvm, to remove the need for having
  that toolchain installed to automagically build BPF scriptlets that then
  gets uploaded to the kernel via sys_bpf() (Wang Nan)
