I don't think symbolic offsets would work, if that's what you mean.
We need to know the constant offset so that (a) we can enforce
TARGET_{MIN,MAX}_ANCHOR_OFFSET (which is more important for other
targets than it is for PowerPC) and (b) we know for PowerPC-like
setups whether the offset needs an addis.
