Ingo reported (again!) that 'make clean' on perf/traceevent does not
work due to some reason with system header file. Quotes Ingo:

 "Note that the old dependency related build failure thought to be
  fixed in commit 860df5833e46 is back:

   make[1]: *** No rule to make target
   `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'.  Stop.

  'make clean' itself does not work in libtraceevent:

   comet:~/tip/tools/lib/traceevent> make clean
   make: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'.  Stop.

  So I had to clean it out manually:

   comet:~/tip/tools/lib/traceevent> git ls-files --others | xargs rm
   comet:~/tip/tools/lib/traceevent>

  and then things build fine."

Try to fix it by excluding system headers from dependency generation.
