* elf.c (merge_sections_remove_hook): New function. (_bfd_elf_merge_sections): Pass it as 3rd argument to _bfd_merge_sections. * libbfd-in.h (_bfd_merge_sections): Add 3rd argument. * libbfd.h: Rebuilt. * merge.c (_bfd_merge_sections): Add remove_hook argument. Call remove_hook if a SEC_EXCLUDE section is encountered.
