cross compilation fails for tree-sitter crate

[hgy59]

There was already an issue with tree-sitter some time ago (reported in #3237).

We use the synology toolchains to build packages for synology devices.

As reported in SynoCommunity/spksrc#6338 (comment) it is not possible to create the tree-sitter crate except for x64 archs.
The error comes from a CFLAG (-m64) that is valid for x64 archs only.

As there are binaries for aarch64 in the release section (like helix-24.07-aarch64-linux.tar.xz) I am just wondering how those are created.

Any instructions are welcome.

The releases are all created by this actions workflow: https://github.com/helix-editor/helix/blob/master/.github/workflows/release.yml

The aarch64 builds use cross and target aarch64-unknown-linux-gnu
