Subject: [PATCH 1/4] tools/perf/build: Implement summary output for 'make clean'

'make clean' used to show all the rm lines, which isn't really informative
in any way and spams the console.

Implement summary output:

  comet:~/tip/tools/perf> make clean
   CLEAN libtraceevent
   CLEAN liblk
   CLEAN config
   CLEAN core-objs
   CLEAN core-progs
   CLEAN core-gen
   CLEAN Documentation
   CLEAN python

'make clean V=1' will still show the old, detailed output.
