aarch64 support

[Mindavi]

Hey, I was wondering if support for aarch64 is planned. This package is a dependency of hydra (https://github.com/nixos/hydra), and I'd like to be able to build hydra for aarch64 as it did before.

However, since upstream added this package as a dependency, I was wondering if it's possible to add aarch64 support.

See https://logs.nix.ci/?key=nixos/nixpkgs.172378&attempt_id=1669bcf6-7b5e-4c57-864d-a2e5569ce24d for the failure log.

Log pasted here for convenience
