Build error if booter is unregisterised
## Summary
If booter/stage0 compiler is unregisterised, then building a registerised compiler fails in all my experiments except in one case. The tests were done on x64 with 8.10.7 as booter and 9.2.3 as target:
```
Booter | Target | Result
------------+-----------+---------
8.10.7+U+H | 9.2.3+R+H | Ok
8.10.7+U+H | 9.2.3+R+M | Fail (*)
8.10.7+U+M | 9.2.3+R+M | Fail (*)
8.10.7+U+M | 9.2.3+R+H | Fail (#)
8.10.7+R+M | 9.2.3+R+H | Ok
U = Unregisterised
R = Registerised
H = Hadrian
M = Make
```
The only working combination I found so far, if the booter is unregisterised, is to use Hadrian in order to build the booter as well as the target compiler. As a sanity check I also gave a registerised booter a chance where I didn't run into any problems.
