Normally, I would have recommended a 2-step deprecate-then-remove
approach, but in this case, I tend to agree with you that we can
remove immediately. I did a little bit of archeology, and found that
this variable appear to have been unused since at least start of CVS.
It was appearing once inside symfile.c:free_named_symtabs, but it was
commented-out so I deleted all that code back in Jan 2010.

So I don't see anyone using this switch today, and it should be fine
just removing it.
