Actually, I take that back!!!

I just realized that this only makes sense if we left the default to
unlimited, but as you saw in my previous message, this is not the case.
So I think we should simply drop the lib/ part of the patch and
just keep the gdb.base/max-value-size.exp part. We'll the wait and
see if any test triggers an unexpected failure on some platforms,
but those would be. But, my guess is that those unexpected failures
might actually be indicative of a real issue ;-).

Thanks, and sorry for the confusion!
