Subject: [PATCH] tool/perf: fix perf compiling errors

From: Li Zhijian <lizhiijian@...fujitsu.com>

since f045b8c, we failed to build perf with LIBCLANGLLVM=1, this patch is to
fix the following compiling errors

lizhijian@...well-OptiPlex-9020:~/lkp/linux/tools/perf$ make LLVM_CONFIG=/usr/bin/llvm-config-3.9 LIBCLANGLLVM=1
  BUILD:   Doing 'make -j8' parallel build
