[PATCH] D56479: [compiler-rt] Add option to disable libc++ build

[Petr Hosek via Phabricator via llvm-commits]

phosek added a comment.

This also needs to support the runtimes build which defines `HAVE_LIBCXX` variable when libc++ is being built.

Where's `LLVM_TOOL_LIBCXX_BUILD` handled? Searching through the tree, I haven't found any references to `LLVM_TOOL_LIBCXX_BUILD`, I have found a few references to other `LLVM_TOOL_${TOOL}` variables in `llvm/tools` but I haven't found any logic that's consuming them aside from `llvm/test/CMakeList.txt` and `polly/test/CMakeList.txt`.
