See this mailing list thread <https://lists.llvm.org/pipermail/llvm-dev/2021-July/151822.html> for the background. Please also link it in the commit description.

Per the description here <https://lists.llvm.org/pipermail/llvm-dev/2021-July/151844.html> it seems that different architectures do get different build directories, so the symlink creation shouldn't conflict. As I noted in the thread, I would prefer to understand the root cause before applying a workaround or a fix.
Per my current understanding the issue shouldn't be possible and might well be a bug in CMake's Makefile generator since the issue was reported to not occur with Ninja.

If someone could provide me the build directory for the failing build (with the relevant runtimes builds generated) I would be able to understand the issue better.
Also, what CMake version is the issue encountered with?
