x86-64: relocation addend is 64bit

Some routines were using the wrong type (int) in passing addends,
truncating it.  This matters when bit 31 isn't set and the high
32 bits are set: the truncation would make it unsigned where in
reality it's signed (happen e.g. on the x86-64 with it's load
address at top-2GB).
