gatsby: [v2] gatsby build hangs on WSL Ubuntu

Description

Build hangs on “Building production Javascript and CSS bundles,” after “bootstrap finished.” This doesn’t happen on Gatsby v1, or with gatsby develop.

Steps to reproduce

1. Make a new gatsby site using command: gatsby new tutorial-part-one https://github.com/gatsbyjs/gatsby-starter-hello-world#v2.
2. Run gatsby build.

Expected result

Gatsby should build the production site.

Actual result

Gatsby hangs on “Building production Javascript and CSS bundles.” I let it run for 10 minutes and then quit. This occurs on both the gatsby-cli
