From 2f7d4728dbfd976788f77b8f43d4dc3c718b71b7 Mon Sep 17 00:00:00 2001
From: Yang Yujie <yangyujie@loongson.cn>

Subject: [PATCH] LoongArch: Use /lib instead of /lib64 as the library search
path for MUSL.
gcc/ChangeLog:
* config.gcc: Add a case for loongarch*-*-linux-musl*.
* config/loongarch/linux.h: Disable the multilib-compatible
treatment for *musl* targets.
* config/loongarch/musl.h: New file.
