Subject: [PATCH 06/18] clang: Look inside the target sysroot for compiler
 runtime

In OE compiler-rt and libc++ are built and staged into target
sysroot and not into resourcedir which is relative to clang
driver installation where the libraries are not instlled

Specific to cross compiling the way yocto/OE works
