[leighmcculloch]

There appears to be a variety of issues relating to cross-compiling ring and aarch64: https://github.com/briansmith/ring/issues?q=is%3Aissue+is%3Aopen+aarch64

[leighmcculloch]

It looks like the warp web framework we're using pulls in rusttls and doesn't provide any flexibility on what tls solution is used. There's an issue open on the warp repo about changing their tls impl from 2019, but no engagement on that issue (seanmonstar/warp#189).

It also looks like the jsonrpsee framework we're using pulls in ring too.

In 9f34f6b I've disabled the tls features of both, and that removes the ring dependency and it now builds on Linux aarch64 just fine.

Removing tls from warp is no big deal, as it doesn't need it. Removing tls from jsonrpsee is not a problem today because the rpc server is always local, but it would be a problem when we deploy a remote one since https would be required then. So this probably isn't a viable alternative.

[leighmcculloch]

Woohoo. So the problem isn't ring, the problem was the linker setup.
