I noticed some commits in the tip tree today that seemed as though they
were addressing this problem.  However, I still get a build failure if
I don't clean out the object directory before building tools/perf:

  BUILD:   Doing 'make -j48' parallel build
  GEN      /home/sfr/next/perf/common-cmds.h
  CC       /home/sfr/next/perf/fixdep.o
  LD       /home/sfr/next/perf/fixdep-in.o
  LINK     /home/sfr/next/perf/fixdep
  CC       /home/sfr/next/perf/perf-read-vdso32
  CC       /home/sfr/next/perf/perf-read-vdsox32
make[3]: *** No rule to make target '/home/sfr/next/next/tools/lib/api/fs/debugfs.h', needed by '/home/sfr/next/perf/ui/gtk/browser.o'.  Stop.
/home/sfr/next/next/tools/build/Makefile.build:116: recipe for target 'ui/gtk' failed
make[2]: *** [ui/gtk] Error 2
Makefile.perf:310: recipe for target '/home/sfr/next/perf/gtk-in.o' failed

(/home/sfr/next/perf/ is the object directory)
