[lld] r262026 - Add comment on AMDGPU that the difference has no obvious reason.

Right. All the stuff I saw in the AMDGPU support in the linker seems that
they are not stemmed from architecture-specific requirement but just to
deal with odd design choices of the file format which seems to have caused
by misunderstanding of the regular ELF spec. I don't think it's too late to
fix it -- I want to fix it.
