hm, probably one of these commits:

8a0c4c2843d3 perf tools: Fix libunwind build and feature detection for 32-bit build
28e962b9d79f perf tools: Fix 32-bit cross build
74af377bc25d perf tools: Fix non-debug build
9402802a416c perf tools: Fix test_on_exit for 32-bit build

broke the suppression of the auto-detection messages on repeat invocations 
of 'make', if all testcases pass.

'make' used to display this on repeat invocations:

 comet:~/tip/tools/perf> make
   BUILD:   Doing 'make -j12' parallel build
 comet:~/tip/tools/perf> make
   BUILD:   Doing 'make -j12' parallel build
 comet:~/tip/tools/perf> make
   BUILD:   Doing 'make -j12' parallel build

Now it displays the spammy auto-detection all the time:

comet:~/tip/tools/perf> make
  BUILD:   Doing 'make -j12' parallel build

Auto-detecting system features:
...                     backtrace: [ on  ]
...                         dwarf: [ on  ]

...                stackprotector: [ on  ]
...            stackprotector-all: [ on  ]

maybe a new testcase fails on my box, but is not properly displayed?

Thanks,
