I'm no expert in these matters, but as per e.g. [1] it looks like the 
target "a.out-sunos-big" is not supported by the used `objcopy`.

[1]: https://github.com/yasuoka/openbsd-uefi/issues/1

...and indeed, the `objcopy` currently shipped with binutils v2.31.1 is 
missing "a.out-sunos-big" in the supported targets list.

```
root@ultra-10:~# objcopy -V
GNU objcopy (GNU Binutils for Debian) 2.31.1
[...]

root@ultra-10:~# objcopy -h
[...]

```

...but an older version does include it:
```

[...]

root@ultra-10:~/binutils-2.30-22# objcopy -h
