That's nothing.  If you have patches outstanding for more than six
months, _then_ you should start to get worried.

Anyway, there are a few corner cases I'd like you to check:

- What happens if there are no .sdata or .sbss items at all, but the
  _SDA_BASE_ symbol is still referenced?  Does it still have an
  address corresponding to where .sdata sections would go if there
  were any?

- What happens when building a shared object?  Does the _SDA_BASE_
  symbol still get created with the right value?
