Pull 'make cscope' fix from Michal Marek:
"The kbuild.git#misc pull request introduced a bug that broke make
cscope. Apparently, both the original author and me only tested the
use case that the commit was supposed to improve (make tags/TAGS), and
not the use case that was not supposed (make cscope)."
* 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
tags.sh: Add missing quotes
