Since this is my first time contributing I wanted to keep it simple and I added just one function I tested with ```bash stage3/bin/zig build -p stage4 -Dno-lib -Dno-langref -Denable-llvm=true --search-prefix ~/repos/zig-boostrap/out/native-linux-musl-baseline/ stage4/bin/zig build test-libc -Dlibc-test-path=../libc-test -Dtest-target-filter=x86_64-linux-musl ``` and the tests passed. I'm planning on doing more once I get the hang of it.
