[PATCH] Makefile: fix for compatibility with *emacs ctags

[Emanuele Giaquinta <emanuele.giaquinta@gmail.com>]

Hi,

I've noticed that, starting from linux-2.6.12-rc1, in the top Makefile the
"cmd_tags" variable has been changed in a way incompatible with *emacs ctags.
Since the "--extra" option exists only in "exuberant ctags", it should be
included in the CTAGSF shell variable.
