  perf evsel: Do not access outside hw cache name arrays (2016-08-18 16:39:46 -0300)

----------------------------------------------------------------
perf/urgent fixes:

- Do not access outside hw cache name arrays (Arnaldo Carvalho de Melo)

- Use addr_location::addr instead of ip for entries when unwinding using
  DWARF CFI, fixing the "srcline" information for userspace application
  callchains (Milian Wolff)

- Reinstate strlcpy() header guard with __UCLIBC__, fixing the build
  with uclibc, detected when building for the ARC architecture (Vineet Gupta)

Build stats, now only android-ndk doesn't build with NO_LIBELF=1, as it
doesn't even have libelf to cross build with, and the non-cross builds
build objtool, uClibc and an ARC architecture cross build image are in
the works:
