This was reported via Discord. During Fedora snapshot builds on PPC, a whole lot of watchpoint tests failed. Including the full list here because some aren't obviously watchpoint related but turn out to be:

```
Looking at the logs they all fail with output like:
```
Jul 05 06:25:06 30: error: Watchpoint creation failed (addr=0x10040038, size=8).
Jul 05 06:25:06 check:14'0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Jul 05 06:25:06 31: error: Target supports (0) hardware watchpoint slots.
Jul 05 06:25:06 check:14'0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
We should not be running tests on systems where we can tell there are no watchpoints. Or at least we could do a check at the front of each test and print something to tell the user what choices they have here.
I know there is a category for at least the API watchpoint tests, we use it for Windows on Arm for example. That's opt in though.
