Issue Description:

[Alpine Linux](https://www.alpinelinux.org/about/):
"Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox.

Alpine Linux is built around musl libc and busybox. This makes it smaller and more resource efficient than traditional GNU/Linux distributions. A container requires no more than 8 MB and a minimal installation to disk requires around 130 MB of storage. Not only do you get a fully-fledged Linux environment but a large selection of packages from the repository."

Swift on Alpine Linux could help create powerful embedded solutions.
Swift should be integrated as an Alpine Linux package so that more people can install it easily.
