     needed when producing EFI binaries on x86. It tells

     containing ELF relocation info.  We need this hack in order to
     be able to generate ELF binaries that can be translated into
     EFI applications (which are essentially COFF objects).  Those
     files contain a COFF ".reloc" section inside an ELFNN object,
     which would normally cause BFD to segfault because it would
     attempt to interpret this section as containing relocation
     entries for section "oc".  With this hack enabled, ".reloc"
     will be treated as a normal data section, which will avoid the
     segfault.  However, you won't be able to create an ELFNN binary
     with a section named "oc" that needs relocations, but that's
     the kind of ugly side-effects you get when detecting section
     types based on their names...  In practice, this limitation is
     unlikely to bite.  */
