refs.c: abort ref search if ref array is empty
The bsearch() implementation on IRIX 6.5 segfaults if it is passed NULL for the base array argument even if number-of-elements is zero. So, let's work around it by detecting an empty array and aborting early. This is a useful optimization in its own right anyway, since we avoid a useless allocation and initialization of the ref_entry when the ref array is empty.
