I'll fix this after lunch, but please try:

  make -C tools/perf build-test

Before pushing patches :-)

In this case this failed:

We need to improve this, but to see the problem I've been doing:

  cp tools/perf/tests/perf-targz-src-pkg /tmp

 then editing the local copy to remove the output redirection to NULL for
the make command, the test uses just the exit return :-\
