Excuse me, I have reverted it in r263636.

----------------
"clang/Config/config.h" doesn't have it and "llvm/Config/config.h" should be unavailable in clang tree.

I suggest you may do;

  # Move it to LLVMSupport.
  # Detect HAVE_REALPATH in clang's cmakefiles.
  # Export HAVE_REALPATH into llvm-config.h.
