[PATCH] D11963: Create a __config_site file to capture configuration decisions.

[Eric Fiselier via cfe-commits]

EricWF added a comment.

I also just realized that this change will currently likely play havoc with how libc++ and libc++abi build together. In order to build libc++ and libc++abi together we would need to

1. Configure libc++ pointing to the libc++abi headers in order to generate the __config_site file.
2. Configure libc++abi pointing it to the libc++ build directory for the headers.
3. build libc++abi
4. build libc++

I'm not quite sure how this would work for an in-tree build.

However if we do things as I suggested above we can keep the current two step build process.
