Most people do this with their own inline asm, but these files should
be sufficient to make syscalls:


I'm not 100% sure they work outside of musl; they might have other
dependencies. Looking at arch/$(ARCH)/syscall_arch.h to see how to
make your own inline-asm syscalls would be a better approach, I think.
