This is wrong. The new declaration cannot be a redeclaration of the old, and at
the same time to be causing Multiversioning. Getting past the early return
(line 11538 with the new code) means the new declaration is causing
Multiversioning, so at this point (line 11554 with the new code) redeclaration
is not possible for the target_version attribute.
