Subject: [PATCH] Configure Linux & macOS multi-arch releases using Travis CI
 (#3)

* Test multi arch Travis CI build configuration

* Enable Docker as required for cross compilation

* Use even more arhitecture targets when building

* Disable BSD builds, install ARM cross compiler dependencies

* Fix invalid ARM target tuple

* Use regular cargo commands for x86_64 Linux

* Fix invalid ARM target tuples

* Configure multi-platform releases using Travis CI, move from test builds

* Enable caching for all Linux x86_64 stable builds on Travis CI

* Merge Linux x86_64, macOS and other build arch logic with an if-statement

* Add missing arch architecture release configuration

* Enable cache on all CI jobs, with platform/arch/version cache separation

* Don't explicitly set cache name, it's automatically inferred
