perf python: More portable way to make CFLAGS work with clang
The existing code that tries to make CFLAGS compatible with clang
doesn't work with Python 3.
Instead of trying to touch _sysconfigdata.build_time_vars directly,
change the dictionary returned by disutils.sysconfig.get_config_vars().
This works on both Python 2 and Python 3.
