 glibc 2.40, since glibc 2.40 has improved fortyfying this
 function with clang, it ends up with build errors like below

librdmacm/preload.c:796:9: error: at most one overload for a given name may lack the 'overloadable' attribute
|   796 | ssize_t recvfrom(int socket, void *buf, size_t len, int flags,
|       |         ^
| /mnt/b/yoe/master/build/tmp/work/core2-64-yoe-linux/rdma-core/51.0/recipe-sysroot/usr/include/sys/socket.h:163:16: note: previous unmarked overload of function is here
|   163 | extern ssize_t recvfrom (int __fd, void *__restrict __buf, size_t __n,
|       |                ^
