I think that we shouldn't use linux strcoll at all. It will not do what 
is needed. The default locale (on startup) of all c applications is "C", 
in this locale strcoll behaves exactly the same as strcmp.

If a partial implementation is needed by an application I would suggest 
something like this:
int strncoll(char *str1, char *str2, int count)
    /* FIXME: handle collates */
    return strncmp(str1, str2, count);
