wasm-pack: wasm-pack can't install wasm32-unknown-unkonwn target on DragonFly BSD

🐛 Bug description

Following the hello world tutorial example, I seem to hit 32bit requirements on a 64bit only operating system.

The following was observed, and annotated in another issue here:

I tried building off commit badbe1c, as well as off the 0.6.0 tag and the 0.7.0 tag, all failed. This was as well with the hello world example.

In order: 0.6.0, 0.7.0, master

🤔 Expected Behavior

I expected that the hello world example would work out of the box, but it’s possible that the documentation is not explicit that only 32bit compilation is supported and/or that 32bit libraries are required and/or that rustup support is required with 32bit binaries and libraries for this.

👟 Steps to reproduce

I did a git clone of the wasm-pack-template (my version of cargo does not support generate), so I then edited the Cargo.toml for an arbitrary author name and project name.

I installed the latest release of wasm-pack by cargo (0.6.0 as of this morning) and tried to do wasm-pack build, after not working and finding an issue exhibiting what I thought was the issue, checked out the source and did a git checkout of 0.7.0, with the a similar error. I then checked out master and tried on master with the same error as on 0.7.0.
