Ninja

Ninja is a small, focused build system designed for speed. Used as the backend for CMake, Meson, and the Chromium/LLVM build systems.

`apt install ninja-build` exists but ships older versions. More importantly, when building Ninja as part of a bootstrapped toolchain environment, having a prebuilt binary avoids circular dependencies. Ninja is a prerequisite for building LLVM, CMake from source, and many other tools.
