Currently musl's getdents64 is an alias for getdents, but the API is
different. According to man page[1], the 2nd arguments of getdents64
is void* instead of struct dirent*.
    ssize_t getdents64(int fd, void *dirp, size_t count);
This patch adds type cast to the redirect macro for API compatibility.
