Got stuck trying to get the 'clean' target done, argh, makefiles, trying
to use the OUTPUT_FEATURES to add a clean target on
tools/perf/config/Makefile, but then if I call it from the main
makefile... it will do feature detection again...

So I think I'll have to redefine it on the main Makefile to avoid having
to call tools/perf/config/Makefile again, right?

Anyway, after lunch I'll try again.
