bug#18235: emacs -nw still depends on libXcursor.so.1

[積丹尼 Dan Jacobson]

$ emacs -nw -q
emacs: error while loading shared libraries: libXcursor.so.1: cannot open 
shared object file: No such file or directory

True, my system is broken today.
However perhaps to increase resilliance,
maybe if the user uses -nw,
perhaps that X stuff can not be attempted to get pulled in.

That way a single emacs binary,
would also be useful,
for those days when one is repairing their system.

So no need to install a separate emacs-non-x package...
when in fact the system might be in such bad shape to make installation 
impossible, etc.
