Support %Lx, %Lu, %Ld in _bfd_error_handler format
One way to print 64-bit bfd_vma or bfd_size_type values on 32-bit
hosts is to cast the value to long long and use the 'll' modifier in
printf format strings. However, that's awkward because we also
support the Microsoft C library printf that uses 'I64' as a modifier
instead, and having variants of translated strings would not endear us
to the translation project. So, rewrite the 'll' modifier in
_doprint for Microsoft. Even with that capability it's not so nice
for 32-bit code to need casts to long long, so this patch makes 'L' a
modifier for bfd_vma rather than an alias for 'll'.
I've then used the new 'L' modifier to fix selected format strings.
* bfd.c (_doprnt): Rewrite "ll" and "L" modifiers to "I64" for
__MSVCRT__. Support "L" modifier for bfd_vma. Formatting.
* elf.c (setup_group): Use "Lx" to print sh_size.
(_bfd_elf_setup_sections): Remove unnecessary cast and print
unknown section type in hex.
(copy_special_section_fields): Style fix.
(bfd_section_from_shdr): Correct format for sh_link. Use a
common error message for all the variants of unrecognized
section types.
(assign_file_positions_for_load_sections): Use "Lx" for lma
adjust error message.
(assign_file_positions_for_non_load_sections): Formatting.
(rewrite_elf_program_header): Formatting. Use "Lx" for
bfd_vma values in error messages.
* elfcode.h (elf_slurp_reloc_table_from_section): Cast
ELF_R_SYM value to type expected by format.
* elflink.c (elf_link_read_relocs_from_section): Use "Lx"
in error messages.
(elf_link_add_object_symbols): Use "Lu" for symbol sizes.
(elf_link_input_bfd): Use "Lx" for r_info.
(bfd_elf_gc_record_vtinherit): Use "Lx" for offset.
