+From: Bernhard Rosenkraenzer <bernhard.rosenkraenzer.ext@huawei.com>
+Subject: [optee-os-stm] Fix build with clang
+
+Fix build with clang: No suffix to RCC_MP_ENCLRR_OFFSET (it's used
+in assembly code), fix warning in mbedtls, look for compiler-rt
+inside the sysroot instead of on the system
+
+Signed-off-by: Bernhard Rosenkraenzer <bernhard.rosenkraenzer.ext@huawei.com>
