cannot build for target x86_64-unknown-linux-musl

[EverlastingBugstopper]

Hey y'all! I'm not sure if this is intended or documented somewhere but it seems as if rusty_v8 does not play well with musl-tools. (It looks like y'all are currently only building for x86_64-unknown-linux-gnu so this issue may just be out of scope).

I've made a minimally reproducible example with this repo that includes rusty_v8 as a dependency, and prints Hello, World.

I have a GitHub Action set up to build this crate with the following steps:

name: Build Release

on: push
    
jobs:
  build:
    name: Repro compilation bug
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2

      - name: Install musl-tools
        run: |
          sudo apt-get update -y
          sudo apt-get install musl-tools -y

      - name: Install rust
        run: |
          rustup target add x86_64-unknown-linux-musl 

      - name: Build
        run: cargo build --verbose --target x86_64-unknown-linux-musl

The Build step fails with the following error

$ cargo build --verbose --target x86_64-unknown-linux-musl
