When compiling the perf tool, it is possible to have get_current_dir_name(), eventfd(), and gettid() provided by the user's development environment. So it is necessary to check whether these functions are available before using them. Meanwhile, bison uses "%define api.pure full" instead of "%pure-parser". This change should also be done in the perf code to compile the perf tool.
