Thanks for your working.

`LLVM_ENABLE_DEBUGLOC_COVERAGE_TRACKING` is `"DISABLED"` by default, and in this case, `#cmakedefine01 LLVM_ENABLE_DEBUGLOC_COVERAGE_TRACKING` reflects the result as `1`.

I am using 3.23.1. Looks like `"DISABLED"` isn't still "false-like string".

Let me fix it to fix `HandleLLVMOptions.cmake` side.
