One small correction to use Static AArch64 relocations to match https://github.com/ARM-software/abi-aa/blob/main/aaelf64/aaelf64.rst#static-aarch64-relocations otherwise LGTM.

It is true that the full definition of the AUTH relocations are in the PAuthABI. They should be mentioned in aaelf64 too as I recently merged that change. Currently checking aaelf64 it looks like there's a couple of mistakes that I've created https://github.com/ARM-software/abi-aa/pull/254 to fix.

Given that PAuthABI is needed to understand the relocations I think it is fine to have this as the canonical reference.
