Check which perf features are enabled.
The PERF_FEATURES_ENABLE variable lists the perf features to
enable. Override it if you want something different from what's
listed above, which is the default. If empty, the build won't
enable any features (which may be exactly what you want, just a
barebones perf without any extra baggage, what you get if you
specify an empty feature list).
Available perf features:
perf-scripting: enable support for Perl and Python bindings
perf-tui: enable support for the perf TUI (via libnewt)
