/* If we are creating a shared library, and this is a reloc
against a global symbol, or a non PC relative reloc
against a local symbol, then we need to copy the reloc
into the shared library. However, if we are linking with
-Bsymbolic, we do not need to copy a reloc against a
global symbol which is defined in an object we are
including in the link (i.e., DEF_REGULAR is set). At
this point we have not seen all the input files, so it is
possible that DEF_REGULAR is not set now but will be set
later (it is never cleared). In case of a weak definition,
DEF_REGULAR may be cleared later by a strong definition in
a shared library. We account for that possibility below by
storing information in the relocs_copied field of the hash
table entry. A similar situation occurs when creating
shared libraries and symbol visibility changes render the
symbol local.
If on the other hand, we are creating an executable, we
may need to keep relocations for symbols satisfied by a
dynamic library if we manage to avoid copy relocs for the
symbol. */

EFI applications (which are essentially COFF objects). Those

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
