  perf symbols: Check compatible symtab type before loading dso (2014-02-24 16:25:01 -0300)

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

. Add support for the new DWARF unwinder library in elfutils (Jiri Olsa)

. Fix build race in the generation of bison files (Jiri Olsa)

. Further streamline the feature detection display, trimming it a bit to
  show just the libraries detected, using VF=1 gets a more verbose output,
  showing the less interesting feature checks as well (Jiri Olsa).

. Check compatible symtab type before loading dso (Namhyung Kim)

. Check return value of filename__read_debuglink() (Stephane Eranian)
