perf tools: Do not display extra info when there is nothing to build

Browse source

Even with fully built tree, we still display extra output when make is
invoked, like:

  $ make
    BUILD:   Doing 'make -j8' parallel build
    DESCEND  plugins
  make[3]: Nothing to be done for 'plugins/libtraceevent-dynamic-list'.

Changing the make descend directly to plugins directory, which quiets
those messages down.
