该PR为回合bugfix:sanitizer: Fix asan against glibc 2.34 [PR100114]
Reference: https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=d9f462fb372fb02da032cefd6b091d7582c425ae

经验证，此commit可解决openEuler 22.03 LTS GCC 10.3.1 + GLIBC 2.34无法正常使用地址消毒功能的BUG，可以使用如下方法验证(参考https://bugzilla.redhat.com/show_bug.cgi?id=1950244#c4)：
1. `yum install -y gcc libasan libasan-static`
2. `printf "int main(void) { return 0; }" > test.c`
3. `gcc -o test -g3 -O0 -fsanitize=address -fno-omit-frame-pointer test.c`
4. `./test`

合入commit前执行4：
```
[root@localhost sanitizer-bug]# ./test
==2592823==ERROR: AddressSanitizer failed to allocate 0x0 (0) bytes of SetAlternateSignalStack (error code: 22)
==2592823==Process memory map follows:
...
```
合入commit后执行4，记得设置PATH和LD_LIBRARY_PATH：
```
[root@localhost sanitizer-bug]# ./test
```
可正常使用地址消毒功能。
