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'.
