On MacOS aarch64 it is:

```
p=0x12345689abcdef0
main=0x10286c460
```

And FreeBSD it is:

```
p=0x12345689abcdef0
main=0x201600
```

These results are not the reason there is a lack `0x` before the address. I will not approve this MR to be merged as the output is based on RTEMS tests and the test [`printf` has been wrapped to use `rtems_vprintf`.](https://gitlab.rtems.org/chris/rtems/-/blob/main/cpukit/libtest/testwrappers.c?ref_type=heads#L47)
