[fix] fix the problem that using tsan to compile，BE will stack overflow
when start (#8904)
Currently TSAN can only be compiled using CLang, not GCC.
And when compiling with -o0, stack overflow occurs at startup, issue #8868.
A function definition will be reported missing at compile time, the file
provided in PR #8665 is required.
