Fix _i3_version debugging symbol (#2492) 

The idea was to ensure the symbol would always be present. For that, we need
__attribute__((used)), not __attribute__((unused)). Further, ensure the
variable has static storage, as the used attribute only applies to variables
with static storage. See also http://stackoverflow.com/a/29545417/712014
