* emultempl/pep.em (..._before_parse): initialize pei386_runtime_pseudo_reloc by version 2. (OPTION_DLL_ENABLE_RUNTIME_PSEUDO_RELOC_V1): New option. (OPTION_DLL_ENABLE_RUNTIME_PSEUDO_RELOC_V2): New option. (make_import_fixup): Use relocation size to read addend. * emultempl/pe.em (..._before_parse): initialize pei386_runtime_pseudo_reloc by version 1. (OPTION_DLL_ENABLE_RUNTIME_PSEUDO_RELOC_V1): New option. (OPTION_DLL_ENABLE_RUNTIME_PSEUDO_RELOC_V2): New option. * pe-dll.c (pe-dll.h): Remove useless include. (make_runtime_pseudo_reloc): Change addend to use bfd_vma. Handle the two variants of pseudo-relocation. (pe_create_import_fixup): Change addend to type bfd_vma. Modify for the two pseudo_relocation variants. (runtime_pseudp_reloc_v2_init): New static variable. * pe-dll.h (pe_create_import_fixup): Change addend argument type to bfd_vma. * pep-dll.h (pep_create_import_fixup): Likewise. * NEWS: Add comment.
