Closing in favour of #352609

We should still do both, as Open Watcom has licensing issues.

I’ve merged the other fix, but it’d be good to get this in since otherwise #352608 will stop VirtualBox and the OVA being built on Hydra.

Successfully built on x86_64-linux, thanks! Having to use pre‐built assembly sources is a bit unfortunate, but better than depending on a non‐Free compiler that we get as a binary blob.

BTW, it seems the meta.license is out of date – they’ve moved to GPL 3 with a linking exception for GPL 2 (sadly something we lack an elegant way of representing).
