the GNU version, the value is the negative of the address
of the reloc within section. We try to cope here by
assuming the AMD version, unless the addend is exactly
the negative of the address; in the latter case we assume
the GNU version. This means that something like
.text
nop
jmp i-4
will fail, because the addend of -4 will happen to equal
the negative of the address within the section. The
compiler will never generate code like this.
