Change the behaviour of the --only-keep-debug option to objcopy and strip so that the sh_link and sh_info fields in stripped section headers are preserved.
bfd * elf.c (_bfd_elf_copy_private_bfd_data): Copy the sh_link and
sh_info fields of sections whose type has been changed to
SHT_NOBITS.
bin * doc/binutils.texi: Document that the --only-keep-debug option
to strip and objcopy preserves the section headers of stripped
sections.
tests * binutils-all/objcopy.exp (keep_debug_symbols_and_check_links):
New proc. Checks that debug-info-only binaries retain the
sh_link field in stripped sections.
