Fix copying Solaris binaries with objcopy.
PR target/19938
bfd * elf-bbfd.h (struct elf_backend_data): New field:
elf_strtab_flags.
New field: elf_backend_set_special_section_info_and_link
* elfxx-target.h (elf_backend_strtab_flags): Define if not already
defined.
(elf_backend_set_special_section_info_and_link): Define if not
already defined.
(elfNN_bed): Use elf_backend_set_special_section_info_and_link and
elf_backend_strtab_flags macros to initialise fields in structure.
* elf.c (_bfd_elf_make_section_from_shdr): Check for SHF_STRINGS
being set even if SHF_MERGE is not set.
(elf_fake_sections): Likewise.
(section_match): New function. Matches two ELF sections based
upon fixed characteristics.
(find_link): New function. Locates a section in a BFD that
matches a section in a different BFD.
(_bfd_elf_copy_private_bfd_data): Copy the sh_info and sh_link
fields of reserved sections.
(bfd_elf_compute_section_file_positions): Set the flags for the
.shstrtab section based upon the elf_strtab_flags field in the
elf_backend_data structure.
(swap_out_syms): Likewise for the .strtab section.
* elflink.c (bfd_elf_final_link): Set the flags for the
.strtab section based upon the elf_strtab_flags field in the
elf_backend_data structure.
* elf32-i386.c (elf32_i386_set_special_info_link): New function.
(elf_backend_strtab_flags): Set to SHF_STRINGS for Solaris
targets.
(elf_backend_set_special_section_info_and_link): Define for
Solaris targets.
* elf32-sparc.c: Likewise.
* elf64-x86-64.c: Likewise.
binutils* testsuite/binutils-all/i386/compressed-1b.d: Allow for the
string sections possibly having the SHF_STRINGS flag bit set.
* testsuite/binutils-all/i386/compressed-1c.d: Likewise.
* testsuite/binutils-all/readelf.s: Likewise.
* testsuite/binutils-all/readelf.s-64: Likewise.
* testsuite/binutils-all/x86-64/compressed-1b.d: Likewise.
* testsuite/binutils-all/x86-64/compressed-1c.d: Likewise.
gas * testsuite/gas/i386/ilp32/x86-64-unwind.d: Allow for the string
sections possibly having the SHF_STRINGS flag bit set.
* testsuite/gas/i386/x86-64-unwind.d: Likewise.
