Support for Alpine Linux

[accnops]

Is your feature request related to a problem? Please describe.
Currently, there is no Alpine Linux support.

When using following example:

File index.js:

require('aws-crt');

File Dockerfile:

FROM node:12.16.2-alpine
RUN apk add gcompat
RUN npm install aws-crt@1.1.3
COPY index.js .
CMD ["node", "index.js"]

Command:
docker build -t aws-crt-test . && docker run aws-crt-test

It seems like aws-crt is "hijacking" the process, and printing:

Signal received: 32, errno: 0
Signal received: 1530847424, errno: 32668

...

And then exiting.

Describe the solution you'd like
Apparently, it's because there's not yet an alpine target where it's linked against libmusl. That would be great, since I can then use this library on Alpine.

Update: This is a feature that we are still interested in adding but we have not gotten to it yet. We will update in the future if our priorities change.

@jmklix any update on your roadmap? From my experience, Alpine is a pretty common base image for Node containers so I'd imagine this would be a common blocker for other teams, as it is for mine.

Adding a reference to what base images do work would be a massive help - or any other workarounds you could suggest!

Initial alpine support has been added to the CRT package and incorporated into the SDK as of the https://github.com/aws/aws-iot-device-sdk-js-v2/releases/tag/v1.16.0 release
