You are right.  The code is a bit more subtle than I thought.

We do clear want_gotx, and set changed_got if !want_got.  Thus it
appears the .got can reduce in size if all of the references to a
variable are via relaxed LTOFF22X relocs.

I agree that the size of rela.got does not seem to matter here.
