Subject: [PATCH] static-build: Add scripts to build content from src/tools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As we'd like to ship the content from src/tools, we need to build them
in the very same way we build the other components, and the first step
is providing scripts that can build those inside a container.
