+Subject: [PATCH] clang: driver: Add dyld-prefix when checking sysroot for ldso
+ path
+
+ * the dyld-prefix shall be taken into account when the default
+   path for the dynamic linker has to be checked.
+
+ * this patch shall be used as annex to the next patch:
+   'clang: driver: Check sysroot for ldso path' which includes
+   the usrmerge scenario.
