[PATCH] D107799: [CMake] Enable LLVM_ENABLE_PER_TARGET_RUNTIME_DIR by default on Linux

[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo added a comment.

This also broke the libcxx CI, see e.g. this scheduled build (regular builds of the main branch): https://buildkite.com/llvm-project/libcxx-ci/builds/5060#5ca44812-fb35-4984-9e08-af785d5b9c81

That ends up with errors like these:

  /home/libcxx-builder/.buildkite-agent/builds/c06bce848068-1/llvm-project/libcxx-ci/build/generic-cxx17/include/c++/v1/__config:13:10: fatal error: '__config_site' file not found

You should be able to reproduce this by just invoking `libcxx/utils/ci/run-buildbot generic-cxx17` in the llvm-project root directory.

I think we need to revert this for now, to unblock libcxx.
