Add r-completion.elc to Makefile

[dickoa]

ess-r-completion is not byte-compiled therefore not sent to /usr/share/emacs/site-lisp for people using make install it creates some problem

Thank you.
The reason this was never detected: It seems that all ESS core developers work out of the build directory and never use 'make install' ... which is at least true for me. ;-)

Thanks Ahmadou. I always keep forgetting about makefiles :(

[mmaechler]

Actually. There's more broken:

cd lisp
\rm -f *.elc
make

very quickly ends in an error that `cl-lib is not found .... which is a bit strange, as interactively it is found well when (require 'cl-lib) is encountered inside ess-completion.el

I'd be grateful for another patch ... as I'm not detecting where the problem is (Emacs 24.3).

I can't reproduce this error on a fresh install from the latest commit.

My specs are the following
Emacs version: GNU Emacs 24.4.1
Linux version (Arch Linux): Linux dickoa 3.18.6-1-ARCH #1 SMP PREEMPT Sat Feb 7 08:44:05 CET 2015 x86_64 GNU/Linux

But I will continue to dig further into this but

I think cl-lib was introduced in 24.4. I have changed it to the old (require 'cl).
