My old shell scripts used to enable it for testing RTEMS and as part of building Ada.

I doubt it had any other users. Its primary value was checking cleanliness of cpukit but with Arm having variants which don't build and no one wants to fix even as workaround, it is of diminishing utility.

Agreed. Ada and Go require being built after RTEMS. I don't recall for gcj but the scripts know. :)
