PR26330, Malloc size error in objdump
PR 26330
* elf.c (_bfd_elf_get_symtab_upper_bound): Sanity check symbol table
size against file size. Correct LONG_MAX limit check.
(_bfd_elf_get_dynamic_symtab_upper_bound): Likewise.
(_bfd_elf_get_reloc_upper_bound): Don't check file size if writing.
(_bfd_elf_get_dynamic_reloc_upper_bound): Likewise.
* elf64-x86-64-.c (elf_x86_64_get_synthetic_symtab): Use
bfd_malloc_and_get_section.
