INITFN does not seem to be a .globl symbol so it's not exported
from the object.

I don't think so.  Since INITFN is not global, the reloc can't
reference it.  So instead, the reloc uses .text+4; I'm assuming
that the assembler placed a value of 4 in the .long.

Does the reloc change if you add .globl INITFN ?
