[PATCH] LoongArch: Fix module relocation error with binutils 2.41

From: Huacai Chen
Date: Mon Jul 10 2023 - 00:30:28 EST


Binutils 2.41 enable linker relaxation by default, but kernel module
loader doesn't support that, so disable it. Otherwise we get such an
error when loading modules: "Unknown relocation type 102".
