I wonder if the existing logic is sufficient?
```cmake
if(CMAKE_SYSTEM_NAME MATCHES "BSD|Linux|OS390|AIX")
set(LLVM_ENABLE_PER_TARGET_RUNTIME_DIR_default ON)
else()
set(LLVM_ENABLE_PER_TARGET_RUNTIME_DIR_default OFF)
endif()
set(LLVM_ENABLE_PER_TARGET_RUNTIME_DIR
${LLVM_ENABLE_PER_TARGET_RUNTIME_DIR_default} CACHE BOOL
"Enable per-target runtimes directory")
