sh: Avoid exporting unimplemented syscalls.
Browse files Browse the repository at this point in the history 
Now that userspace is making use of kernel-provided sanitized headers for
working out supported interfaces, we need to be a bit more diligent with
matching the syscall definitions with their actual wiring/support state.

In theory it shouldn't hurt anything since sys_ni_syscall will ultimately
do the right thing, but there's also not much need to lie about legacy
x86 syscalls that we've never supported.

This tightens things up a bit for uClibc at least.
