  tools build: Fix cross compile build (2015-10-13 11:59:43 -0300)

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

User visible:

- Use the alternative with the most descriptive filename containing
  a vmlinux file for a given build-id, providing a better title line
  for tools such as 'annotate' (Arnaldo Carvalho de Melo)

- Remove help messages about previous right and left arrow keybidings, that
  were repurposed for horizontal scrolling (Arnaldo Carvalho de Melo)

- Inform how to reset the symbol filter in the hists browser (top & report)
  (Arnaldo Carvalho de Melo)

- Add 'm' key for context menu display in the hists browser, that became
  inacessible with the repurposing of the right arrow key for horizontal
  scrolling (Namhyung Kim)

- Use debug_frame for callchains if eh_frame is unusable (Rabin Vicent)

Build fixes:

- Fix strict-aliasing breakage with gcc 4.4 in the READ_ONCE/WRITE_ONCE code
  adopted from the kernel tree, that builds with -fno-strict-aliasing while
  tools/perf/ uses -Wstrict-aliasing=3 (Jiri Olsa)

- Fix unw_word_t pointer casts in code using libunwind for callchains,
  fixing the build in at least 32-bit MIPS systems (Rabin Vicent)

- Workaround cross compile build problems related to fixdep (Jiri Olsa)
