Fixed cross-compiling by replacing wget with curl (#1759)
Fixed cross-compiling by replacing wget with curl (#1759)

It looks like the default docker image used by cross doesn't have
wget installed. This causes builds to fail. This can be fixed by
switching to curl.

## Issue Addressed
cross-compiling was broken (at least for build-aarch64)

## Proposed Changes
swap wget for curl
