Merging SHF_LINK_ORDER sections can affect semantics if the sh_link fields point to different sections. Specifically, for SHF_LINK_ORDER sections, the sh_link field acts as a reverse dependency from the linked section, causing the SHF_LINK_ORDER section to be included if the linked section is included. Merging sections with different sh_link fields will cause the entire contents of the SHF_LINK_ORDER section to be associated with a single (arbitrarily chosen) output section, whereas the correct semantics are for the individual pieces of the SHF_LINK_ORDER section to be associated with their linked output sections. As a result we can end up incorrectly dropping SHF_LINK_ORDER section contents or including the wrong section contents, depending on which linked sections were chosen.
