+Subject: [PATCH 2/2] llvm: allow env override of exe path
+
+When using a native llvm-config from inside a sysroot, we need llvm-config to
+return the libraries, include directories, etc. from inside the sysroot rather
+than from the native sysroot. Thus provide an env override for calling
+llvm-config from a target sysroot.
