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)
