Testing Capacity's compiler toolchain using QEMU

First, necessary component need to be downloaded and setup. Run the following:

./setup.sh

This script will download necessary dependencies, which includes LLVM 14.0.0, Musl into /tmp and extract the components into $(pwd)/build directory.

Then, build Capacity components with:

./build.sh

Build and run tests with

./run.sh test toolchains
