// Each assembler created .ARM.exidx section has the SHF_LINK_ORDER flag set
// with the sh_link containing the section index of the executable section
// containing the function it describes. To maintain this property in
// relocatable links we pass through the .ARM.exidx section, the section it
// it has a sh_link to, and the associated relocation sections uncombined.
