Subject: [PATCH 143/161] perf tools: Separate lbfd check out of NO_DEMANGLE condition

From: Jiri Olsa <jolsa@...hat.com>

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.
