Apparently there is some issue with following a double symlink path, e.g. llvm.src/tools/clang is a symlink to ../../cfe.src, while llvm.src/tools/clang/tools/extra (which really is under ../../cfe.src/tools) is a symlink to ../../clang-tools-extra.src.

Oh, I thought it was a CMake vs. autoconf thing, and we were just
symlinking clang-tools-extra wrong (see r257905). I guess I jumped to
wrong conclusions there :-/

Actually, I use export.sh for creating the tarballs, so that's not a
problem. Maybe just exporting into the right directories is the way to
