I hit the same problem following the instructions at https://clang.llvm.org/docs/AddressSanitizer.html#how-to-build. However if instead I use -DLLVM_ENABLE_PROJECTS="clang;compiler-rt" and drop the -DLLVM_ENABLE_RUNTIMES argument, I'm able to build asan without issue. So perhaps this is just a documentation issue?
