FreeBSD/arm64 installation doesn't work: unknown architecture arm64

[alt-romes]

I tried to use the get-ghcup.haskell.org script to install ghcup on a FreeBSD arm64 VM.

It failed with:

Press ENTER to proceed or ctrl-c to abort.
Note that this script can be re-run at any given time.

Unknown architecture: arm64
