Yeah, allocate_symtab does that automatically.

I'm a little tempted not to have a symtab there at all, instead just
having a special block (or even a special dictionary) that isn't
associated to a symtab. That, however, runs into the issue of what to
do with the 'symtab' argument to lookup_symbol in that case; we could
set it to NULL, but in that case GDB might crash if some silly user
typed 'break NamespaceName'. Or something.
