There is racing in Makefile. I see following output:
...
CC /xx/xx/perf/1.0-r8/perf-1.0/util/callchain.o
CC /xx/xx/perf/1.0-r8/perf-1.0/util/values.o
CC /xx/xx/perf/1.0-r8/perf-1.0/util/debug.o
make[3]: *** No rule to make target
`/xx/xx/perf/1.0-r8/perf-1.0/util/syscalltbl.o'. Stop.
make[3]: *** Waiting for unfinished jobs....
CC /xx/xx/perf/1.0-r8/perf-1.0/util/machine.o
CC /xx/xx/perf/1.0-r8/perf-1.0/util/map.o
...
The error disappeareafter doing 'make archheaders' before 'make all'.
Thank you.
