    perf tests: Fix tarpkg build test error output redirection · cde88355
    Arnaldo Carvalho de Melo authored
    So we need to trow away just stdout, leaving stderr to be caught by
    the build tests infrastructure, so that we can see what went wrong
    when the tarpkg build test fails:
    
      $ make -C tools/perf build-test
      make: Entering directory '/home/acme/git/linux/tools/perf'
      - tarpkg: ./tests/perf-targz-src-pkg .
      tests/make:302: recipe for target 'tarpkg' failed
      make[1]: *** [tarpkg] Error 2
      Makefile:102: recipe for target 'build-test' failed
      make: *** [build-test] Error 2
      make: Leaving directory '/home/acme/git/linux/tools/perf'
      $ cat tools/perf/tarpkg
      ./tests/perf-targz-src-pkg .
        PERF_VERSION = 4.5.g05f5ec
        PERF_VERSION = 4.5.g05f5ec
      In file included from bench/mem-memcpy-x86-64-asm.S:9:0:
      bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory
      compilation terminated.
      mv: cannot stat ‘bench/.mem-memcpy-x86-64-asm.o.tmp’: No such file or directory
      make[5]: *** [bench/mem-memcpy-x86-64-asm.o] Error 1
      make[5]: *** Waiting for unfinished jobs....
      make[4]: *** [bench] Error 2
      make[4]: *** Waiting for unfinished jobs....
      make[3]: *** [perf-in.o] Error 2
      make[3]: *** Waiting for unfinished jobs....
      make[2]: *** [all] Error 2
      $
    
    So the test flow is:
    
    1. Run: 'make -C tools/perf build-test'
    
    2. One of its tests failed, in this case, the 'tarpkg' one
    
    3. Look at what went wrong, by looking at the output of that test, in
       tools/perf/tarpkg
    
    Admittedly, this should be shortcircuited to showing what went wrong directly
    from the 'make build-test' step, but lets first fix this tarpkg one and the
    problem it spotted, which should be fixed by adding some extra file to the
    tools/perf/MANIFEST so that detached tarballs continue being self contained and
    build successfully.
