Description
In this case, the var_128 variable should be the argument of j_strlen(), which is proved by seeing the source code, but Binja cannot identify the correct arg. Probably is the function type isn't applied properly?

Research direction
Start with the issue's GNU_IFUNC example, the attached image, and the referenced j_strlen() call. Compare the source-level argument with Binary Ninja's inferred argument and trace how static-linked GNU_IFUNC symbols are analyzed. Done means the correct var_128 argument is identified for this case and the behavior is covered by a reproducible check.
