Michael Sproul 379664a648 Improve compilation error on 32-bit (#2424) 
## Issue Addressed

Closes #1661

## Proposed Changes

Add a dummy package called `target_check` which gets compiled early in the build and fails if the target is 32-bit

## Additional Info

You can test the efficacy of this check with:

```
cross build --release --manifest-path lighthouse/Cargo.toml --target i686-unknown-linux-gnu
```

In which case this compilation error is shown:

```
error: Lighthouse requires a 64-bit CPU and operating system
  --> common/target_check/src/lib.rs:8:1

Overview

Lighthouse is:

  • Ready for use on Eth2 mainnet.
  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
  • Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
  • Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys, the Decentralization Foundation and private individuals.
  • Actively involved in the specification and security analysis of the Ethereum 2.0 specification.

Eth2 Deposit Contract

The Lighthouse team acknowledges 0x00000000219ab540356cBB839Cbe05303d7705Fa as the canonical Eth2 deposit contract address.

Documentation

The Lighthouse Book contains information for users and developers.

The Lighthouse team maintains a blog at lighthouse.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.

Branches

Lighthouse maintains two permanent branches:

  • stable: Always points to the latest stable release.
    • This is ideal for most users.
  • unstable: Used for development, contains the latest PRs.
    • Developers should base their PRs on this branch.

Contributing

Lighthouse welcomes contributors.

If you are looking to contribute, please head to the Contributing section of the Lighthouse book.
