Subject: [patch] perf_counter tools: fix libbfd detection for systems with
libz dependency
perf_counter tools: fix libbfd detection for systems with libz dependency
Due to a libz dependency in some distro's binutils package, demangle
support isn't compiled in despite the necessary libraries being available.
Fix this by adding a -lz link test to the dependency detection rules.
