+From 528aeb42652a3159c1bfd51d6c1442c3ff27b84c Mon Sep 17 00:00:00 2001

+Subject: [PATCH] allow setting sysroot for libgcc lookup
+
+Explicitly pass the new variable LIBGCC_LOCATE_CFLAGS variable when searching
+for the compiler libraries as there's no easy way to reliably pass --sysroot
+otherwise.
+
+Upstream-Status: Pending [https://github.com/OP-TEE/optee_os/issues/4188]
