* Make sure all headers used by lib/System have checks
* Use "standard" autoconf checks for certain problematic headers
For PR432:
* Resurrect --with-llvmgccdir so a specific llvm-gcc/llvm-g++ installation

Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting
rid of reliance upon a symbolic link to switch implementations in lib/System
