helix: Misbeavings with target x86_64-unknown-linux-musl

Reproduction steps

I managed to build helix editor v0.6.0 with target set to x86_64-unknown-linux-musl.

Here’s the Dockerfile. If I extract the binary from the built image and I run it on my Ubuntu 20.04.3 LTS desktop for instance, it works as expected. It did not under the Alpine Linux v3.15.0 container. The theme doesn’t seem to be applied as well as the syntax highlighting.

Build the above Dockerfile:

docker build \
  --file ./Dockerfile \
  --pull -t "<DOCKER-IMAGE-NAME>" .

… and run the container with the following:

docker run --rm -it <DOCKER-IMAGE-NAME> /bin/ash

From within the running container download an example file:

wget https://raw.githubusercontent.com/lanceschi/threejs-ply-loader/develop/tests/index.spec.js

Open it verbosely:

./hx -vvv index.spec.js

Here’s a screenshot:
