+Subject: [PATCH] Correct library search path for OpenEmbedded Host
+
+For OpenEmbedded Host, the gcc install path is
+/usr/lib/x86_64-[distroname]-linux/[gcc-version].
+So the library search path is not found with default triple
+'x86_64-linux-gnu' for x86_64. Causing following error:
+[snip]
+compiler-rt-native/13.0.1-r0/recipe-sysroot-native/usr/bin/clang
+-target x86_64-linux
+-isystem/path/to/x86_64-linux/compiler-rt-native/13.0.1-r0/recipe-sysroot-native/usr/include
