Currently, no.

Problem is that the redisplay engine does not check whether mouse is
over a fringe bitmap, and consequently, it does not try to find the
origin of that bitmap (the overlay string), so it doesn't know where
to find the help-echo string either.  It would be a good thing to
fix this, but it is not trivial.

In any case, I would put the help-echo property into the arglist to the
place where you call gdb-put-string so you avoid the append here.

Like this:
            (gdb-put-string
             ...
             'gdb-bptno bptno
             'gdb-enabled enabled
             'help-echo "...")
