[PATCH] D25354: Treat polly as "in tree" if LLVM_EXTERNAL_POLLY_SOURCE_DIR is provided

[Michael Kruse via llvm-commits]

Meinersbur added a comment.

Did you successfully build Polly out-of-tree with this. with an without LLVM_POLLY_LINK_INTO_TOOLS? I think I remember there were other places where it assumed that polly is in `${LLVM_ROOT}/tools/polly`.
