  perf test: Do not be case sensitive when searching for matching tests (2015-11-06 17:50:04 -0300)

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

- libbpf error reporting improvements, using a strerror interface to
  more precisely tell the user about problems with the provided
  scriptlet, be it in C or as a ready made object file (Wang Nan)

- Do not be case sensitive when searching for matching 'perf test'
  entries (Arnaldo Carvalho de Melo)

- Inform the user about objdump failures in 'perf annotate' (Andi Kleen)

Infrastructure:

- Improve the LLVM 'perf test' entry, introduce new ones for
  BPF and kbuild to check the environment used by clang to
  compile .c scriptlets (Wang Nan)
