think that was an error propagated from the case when
we are going to emit the relocation. If we are not
going to emit the relocation, then we just want to
set add_number to the difference between the symbols.
This is a case that would only arise when there is a
PC relative reference from a section other than .text
to a symbol defined in the same section, and the
reference is not relaxed. Since jump instructions on
the i386 are relaxed, this could only arise with a
call instruction. */
