sh: Avoid exporting unimplemented syscalls.
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. Suggested-by: Carmelo Amoroso <carmelo.amoroso@st.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
