Dynamic Analysis with Clang building python make unittest failed

use this way to enable sanitizers make unittest check Sanitizer failed; it use _cflags to check

_cflags = sysconfig.get_config_var('CFLAGS') or ''
_config_args = sysconfig.get_config_var('CONFIG_ARGS') or ''
MEMORY_SANITIZER = (
    '-fsanitize=memory' in _cflags or
    '--with-memory-sanitizer' in _config_args
)

ADDRESS_SANITIZER = (
    '-fsanitize=address' in _cflags
)

should replace with configure option

  --with-address-sanitizer
                          enable AddressSanitizer memory error detector,
                          'asan' (default is no)
  --with-memory-sanitizer enable MemorySanitizer allocation error detector,
                          'msan' (default is no)
  --with-undefined-behavior-sanitizer
                          enable UndefinedBehaviorSanitizer undefined
                          behaviour detector, 'ubsan' (default is no)

首先定位读取 sysconfig CFLAGS 和 CONFIG_ARGS 的 Python unittest sanitizer 检查。将其与为 AddressSanitizer、MemorySanitizer 和 UndefinedBehaviorSanitizer 列出的 configure 选项进行比较，然后运行 make unittest check，以确认 sanitizer 检测在使用这些选项时能够正常工作。
