/*
* This is an ugly, but unfortunately necessary hack that is
* needed when producing EFI binaries on x86. It tells
* elf.c:elf_fake_sections() not to consider ".reloc" as a section
* 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.
