Add support for removing named sections to objcopy and strip.
* objcopy.c (struct section_list): Define. (remove_sections): New static variable. (strip_options, copy_options): Add remove-section. (copy_usage, strip_usage): Mention -R and --remove-section. (setup_section): If section is in remove_sections list, ignore it. (copy_section): Likewise. (strip_main, copy_main): Handle -R. * binutils.texi, objcopy.1, strip.1: Document new options.
