LNT Compile Patch for review

[Marc Schifer via llvm-commits]

Simple patch to make lnt compile use the target compiler instead of the system compiler for make driven Project tests (non Xcode type). Currently if its not an Xcode target for the projects, it does not export any of the environment variables required to make it use the correct compiler and ends up defaulting to the system compiler.
