It does make sense if another, say libx, possibly incomplete, links
with liba too, and pulls symbols from it that are also defined in
libb. If libtool omits the first `-la' in `-lx -la -lb -la', the
executable will get symbols from -lb instead of from -la.
This all assumes -la is a static library. Should it be shared, we
could hopefully drop multiple occurrences thereof, keeping only the
last one.
