Bug#828766: liblucy-perl: please make the build reproducible

[Dominique Dumont]

My C is quite rusted, but, for what it's worth, I've looked at the patch.

As far as I understand qsort doc, you call this function with a array of 
strings (char *), i.e. a char**.

cmpstringp is called with an object from the array, i.e. a void pointer to a 
char *. I don't think dereferecing the pointer is safe.

I think you should call strcmp with :

strcmp( (const char *) p1, (const char *) p2);

I'll let you test this
