Thanks, seems like the makefiles got hit by the switch to the new 
default for executables with unittests (run test and exit instead 
of `main()`). I've raised a PR to fix this issue: 
https://github.com/dlang/dmd/pull/13585.

You can simply skip the deprecated makefiles and run `rdmd 
src/build.d`.
