The scandir(3) function expects fourth parameter, compar, be in type of:

Browse Source 
int (*compar)(const struct dirent **, const struct dirent **)

The current code defines sortq() to accept two void *, then cast them
to const struct dirent **.  Because the code does not really need this
cast, we can eliminate the casts by changing the function prototype
to match scandir(3) expectation.
