The "minimal symbol table" is built from linker-supplied info.
RT: I moved this check to last, after the complete search of
the global (p)symtab's and static (p)symtab's. For HP-generated
symbol tables, this check was causing a premature exit from
lookup_symbol with NULL return, and thus messing up symbol lookups
of things like "c::f". It seems to me a check of the minimal
symbol table ought to be a last resort in any case. I'm vaguely
worried about the comment below which talks about FORTRAN routines "foo_"
though... is it saying we need to do the "minsym" check before
the static check in this case?
