ia64: restore symbol versions for symbols defined in assembly

Browse Source 
The ia64 build generates many warnings like this:

   WARNING: EXPORT symbol "empty_zero_page" [vmlinux] version generation failed, symbol will not be versioned.

Besides adding the necessary header this also requires fiddling with
some explicit .S -> .o rules.
