Currently, glibc is not enable FSTATAT_USE_STATX in 64 bits system.
Shall we modify sysdeps/unix/sysv/linux/fstatat64.c to support statx like:
===
diff --git a/sysdeps/unix/sysv/linux/fstatat64.c
b/sysdeps/unix/sysv/linux/fstatat64.c
index 2ab914380d..bd3b20644e 100644
--- a/sysdeps/unix/sysv/linux/fstatat64.c
+++ b/sysdeps/unix/sysv/linux/fstatat64.c
@@ -42,7 +42,7 @@ _Static_assert (sizeof (__blkcnt_t) == sizeof

+ || defined STAT_HAS_TIME32 || !defined __NR_newfstatat

static inline int
===
or add fstatat64.c in loongarch port??
By now no other architectures have their own fstatat64.c.
