Liblinux – architecture-independent access to Linux system calls (github.com)

A freestanding C library that allows direct access to syscalls seems like a good thing. This one was x64 + gcc only and is archived, but the idea sounds right. E.g. I'd like access to futex.

A maintained, cross arch alternative to this is nolibc, which resides in the kernel tree. See:
