Hi Tom,
When the feature check fails to build the file `tools/build/feature/test-
llvm.make.output` will be generated which will show the error.
```
test-llvm.cpp:2:10: fatal error: llvm/Support/ManagedStatic.h: No such file or
directory
2 | #include "llvm/Support/ManagedStatic.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
```
