Many embedded systems will not need this syscall, and omitting it
saves space.  Add a new EXPERT config option CONFIG_SENDFILE_SYSCALL
(default y) to support compiling it out.

Nice work, thanks!

If there are no objections, and nobody has a tree they'd rather carry
this through, I'll take the series through the tiny tree when it's ready
to merge.

I think it's rather pointless - there is very little sendfile code,
so you'd rather want to disable splice.

That's the plan, but since sendfile depends on some of the splice bits,
sendfile needs to be optional as well; SENDFILE_SYSCALL will then select
SPLICE_SYSCALLS.
