building ecl fails in case the installed etags is actually exuberant-ctags

[kiwifb]

In some debian installs (and derivatives such as ubuntu) the etags program is actually to ctags from exuberant-ctags. This is incompatible with what ecl expect. the symptoms are as follow:

echo > TAGS
if test "xetags" != "x"; then \
        srcfiles=`find 
/scratch/scratch/schilly/sage/sage-4.6.2/spkg/build/ecl-11.1.1/src/src/c 
/scratch/scratch/schilly/sage/sage-4.6.2/spkg/build/ecl-11.1.1/src/src/h 
-name '*.[chd]'` && \
        etags --language=c    -o TAGS $srcfiles && \
        etags --language=none -o TAGS --append \
              --regex='/@\([-:*a-zA-z]+\)/\1/' \
              --regex='/@(defun \([-:*a-zA-z]+\)/\1/' \
              $srcfiles; \
        fi
etags: relocation error: /usr/lib/libldap_r-2.4.so.2: symbol 

or

echo > TAGS
if test "xetags" != "x"; then \
srcfiles=`find  
/storage/strogdon/gentoo/var/tmp/portage/dev-lisp/ecls-11.1.1/work/ecl-11.1.1/src/c  
/storage/strogdon/gentoo/var/tmp/portage/dev-lisp/ecls-11.1.1/work/ecl-11.1.1/src/h  
-name '*.[chd]'` && \
etags --language=c    -o TAGS $srcfiles && \
etags --language=none -o TAGS --append \
       --regex='/@\([-:*a-zA-z]+\)/\1/' \
       --regex='/@(defun \([-:*a-zA-z]+\)/\1/' \
       $srcfiles; \
fi
etags: Warning: "--language" option is obsolete; use "--language-force"  
instead
etags: "TAGS" doesn't look like a tag file; I refuse to overwrite it.

There is no way to disable the building of TAGS in the configuration and detecting that you have an etags program from emacs is complicated. See the following bug reports:

• http://bugs.gentoo.org/show_bug.cgi?id=357319
• http://sourceforge.net/tracker/?func=detail&aid=3202253&group_id=30035&atid=398053 (upstream)

Here is the new spkg. Basically I touch build/TAGS before make is called so that TAGS is never built. Bypassing any problem with a broken etags or ctags passing for etags.
I will attach a patch for the reviewer with all the changes to the spkg.

Thank you for changing it into a positive review! I was just about to do that myself.
