6502 against a global symbol, or a non PC relative reloc
6503 against a local symbol, then we need to copy the reloc
6504 into the shared library. However, if we are linking with
6505 -Bsymbolic, we do not need to copy a reloc against a
6506 global symbol which is defined in an object we are
6507 including in the link (i.e., DEF_REGULAR is set). At
6508 this point we have not seen all the input files, so it is
6509 possible that DEF_REGULAR is not set now but will be set
6510 later (it is never cleared). We account for that
6511 possibility below by storing information in the
6512 dyn_relocs field of the hash table entry. A similar
6513 situation occurs when creating shared libraries and symbol
6514 visibility changes render the symbol local.
6516 If on the other hand, we are creating an executable, we
6517 may need to keep relocations for symbols satisfied by a
6518 dynamic library if we manage to avoid copy relocs for the
