Where was this when I needed it!
As one of my class projects, I built a Linux compatibility layer for the toy OS we had built, by adding a proper ELF loader and emulating syscalls. I really struggled to get glibc or even musl working, and so I ended up hand-coding some `-nostdlib` programs instead of being able to use coreutils. If nolibc really works as a minimal libc, would have been incredibly cool to be able to run coreutils on my OS!
