      tools/perf/build: Simplify the libelf logic · 5f36978c
      Ingo Molnar authored
      Ulrich Drepper and Namhyung Kim reported that the libelf logic in
      config/Makefile is duplicated in part.
      
      Remove the duplication, and also remove the now unused FLAGS_LIBELF
      variable.

      tools/perf/build: Pass through DEBUG parameter · fcf92585
      Ingo Molnar authored
      Arnaldo reported that 'make DEBUG=1' does not work anymore.
      
      The reason is that 'Makefile' only passes it through to
      'Makefile.perf' via the environment, but 'Makefile.perf'
      checks that it's a command line option:
      
          ifeq ("$(origin DEBUG)", "command line")
            PERF_DEBUG = $(DEBUG)
          endif
      
      So pass it through properly, and also clean up DEBUG parameter
      handling while at it and fix a couple of annoyances:
      
       - DEBUG=0 used to be interpreted as 'debugging on'. Turn it
         into 'debugging off' instead.
      
       - Same was the case for 'DEBUG=' - turn that into debug-off
         as well.
      
       - Pass in just a clean, sanitized 'DEBUG' value and get rid of
         the intermediate, unnecessary PERF_DEBUG variable.

      perf tools: Separate lbfd check out of NO_DEMANGLE condition · 3e6a147d
      Jiri Olsa authored
      We fail build with NO_DEMANGLE with missing -lbfd externals error.
      The reason is that we now use bfd code in srcline object:
        perf tools: Implement addr2line directly using libbfd
      
      So we need to check/add -lbfd always now.
