Try running an original MCC Linux binary and C lib on a current kernel

We've put *entire binary formats* behind a config option. We've put older
syscalls behind it, we've put sysfs behind it, sysctl behind it, the
older microcode interfaces behind it, ISA bus as a concept behind
options. VDSO, IPC, even 32bit support ... the list goes on and on.

I'd say those were far more generic on the whole than splice/sendfile.
