I've landed part of this patch that modifies only CMakeLists.txt in
r230247, and it seemed to fix both your bot (
http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-debian-fast/builds/23461),
and worked on our bot (
http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-autoconf/builds/856
).
