Done.  Yeah, I'm not convinced that the changed search order is
ultimately the correct thing to do either.  What is important for me
right now is to have an easy way to look up a symbol in the global
environment.  Unfortunately, the way minimal symbol lookup is
currently handled screws that up, because it will use static symbols as
a fallback measure.

So ultimately that will have to get sorted out, and we can go with
whatever solution is adopted on the mainline.  And I honestly have no
idea what that solution will be: it seems to me that trying to use all
three of symtabs, psymtabs, and minimal symbols is probably redundant,
but maybe I'm missing something and even if they are I don't have a
solid feeling for the best way to remove some of the redundancy.

For now, I'm adopting the tactic of making sure that things work well
if there's proper debugging info but also making the code modular
enough that that aspect of the search strategy will be easy to
change.
