`nodeenv --prebuilt` on musl libc produces non-working binaries

[asottile]

Easiest reproduction is through using alpine with docker.

$ docker run -ti python:2.7.14-alpine3.7 sh -exc 'pip install nodeenv; nodeenv nenv; . nenv/bin/activate; node --version'
+ pip install nodeenv

sh: node: not found

A workaround (I believe... it's still building) is to build from source:

apk --no-cache add gcc g++ make linux-headers
nodeenv nenv --source  # wait for an eternity

I wonder if we can ignore prebuilt linux binaries if we're not using glibc?

I've additionally created an upstream issue asking for prebuilt binaries -- we'll see! nodejs/nodejs.org#1569

@asottile things seem to work fine if we first apk add nodejs and then pass system as the NODE_VER to create the environment:

❯ docker run -ti python:2.7.14-alpine3.7 sh -exc 'apk add --no-cache nodejs bash && pip install nodeenv && nodeenv -n system nenv && . nenv/bin/activate && node --version && npm --version'

+ apk add --no-cache nodejs bash

Note that I also had to apk add bash because... Alpine.

Now, is there a way to tie this back to https://github.com/pre-commit/mirrors-jshint/issues/4?

woohoo, upstream added musl binaries, I'll take a stab at making this work :)
