6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: WANG Rui wangrui@loongson.cn
commit 13c23cb4ed09466d73f1beae8956810b95add6ef upstream.
This patch fixes a build issue on LoongArch when Rust is enabled and compiled with GCC by explicitly setting the bindgen target and skipping C flags that Clang doesn't support.
